Dosing pumps are one of those pieces of equipment that reef keepers either swear by or never bother with — and I understand both camps. When I set up my 125-gallon reef, manually dosing two-part was manageable at first, but as the coral load grew, consistency became critical. A good dosing pump takes the guesswork out of it completely. The difference in stability I saw after switching was noticeable within weeks.

Looking for the best aquarium dosing pump? It is common to have a lot of buyer anxiety when it comes to buying one. After all, you just graduated into the next level of reefing when you start considering a dosing pump. It is the gateway to advanced reef tanks like LPS and SPS dominated tanks and getting into coral fragging.

This is an exciting time for you. I’ve been in your shoes when I first started with my favorite tanks, The LPS dominated tank. I was going crazy with euphillyas to the point where I needed to dose regularly to keep up my levels. Over my 25 years of experience keeping saltwater tanks, I’ve seen it all and been through the journey you are going through now.

Finding the a dosing pump that is right for you involves several factors. My goal with this post is to help guide you in your decision to make an informed buy. Let’s first talk about what to look for.

What To Look For When Buying An Aquarium Dosing Pump

Before we start comparing dosing pumps, we need to talk about what to look for when purchasing one. Dosing pumps are precision instruments and not every model can stay accurate for long.

Dosing pumps are a premium piece of reef aquarium equipment. It is for advanced reefers and can be a expensive purchase. A solid dosing pump has the potential to automate the supplement schedule of your aquarium. Others can even change your water automatically!

For these dosing pumps I’m reviewing today, this is my criteria:

• Quality
• Features and Accessories
• Brand Name
• Price

Dosing Pumps – A Quick Comparison

Now that we know the criteria I’m looking at, let’s see who makes the cut. The list below are the picks I would be proud to put into my tank setups. They are offered by high quality manufacturers who have been around for years. There is no up and coming venture backed company here. These are all high quality name brand controllers. Let’s continue further below.

In a hurry? I recommend the Neptune DOS!

7 Top Reviewed (2023 Update)

Dosing pumps come in all pieces and quality. Let’s see what these made the cut.

1. Neptune DOS

The Neptune DOS is the most advanced doser on the market today. It is one of only two dosers on the market that is capable of performing automatic water changes. It is designed to function with the Neptune Apex system, which in my aquarium controller review, was named the best controller you can purchase in our hobby.

Because the DOS works off a controller, it has the ability to perform multiple functions. Aside from being able to perform automatic water changes, it can provide provide 2 part dosing and any other type doing like trace elements through the controller.

The DOS separates itself for others with its build quality. The tubing is 3.3mm in diameter, nearly double of the what you see standard. It allows the pump to not only run for shorter amount of time, but also prevent clogging and promotes a longer pump life.

The main issue with the DOS is it requires you to have a Neptune Controller. It won’t run without one. If you are looking for doser with its own controller included, you can look at the other options I review below.

Perfect For – The Reef Junkie

2. Bubble Magus BM-T11

The Bubble Magus Dosing Pump is a dosing all in one dosing pump. It is a self run unit that has German-made medical tubing and is easy for a beginner to use.

The clock feature is easy to setup and program and these units have been known for lasting a long time. They remind me Bubble Magus’ Protein Skimmers, which are seen as value buys in our hobby. Bubble Magus delivers a high end offering with a reasonable price tag with this dosing pump.

The main issue with this pump is the tubing. While it is German-made, the tubing is thin so it is best to replace it once a year. As long as you do that, you shouldn’t have any issues using this doser for the long-term.

Amazing For – The Value Hunter

3. Kamoer X1

I’m a huge fan of the Kamoer X1. When dosers first came out, they were expensive and lacked simplicity. The X1 is the answer to that problem. Not only is it easy to use with its WiFi enabled app, but you can grow with it. The initial investment is very reasonable and as you grow in the hobby you can just buy additional units.

Kamoer will allow you to chain up to 4 of these units within the mobile app. This gives you the flexibility of not just running two part solution for your corals, but also trace elements and macronutrients for those of you who run a low nutrient reef tank. The fact that you can grow into this system makes it an excellent choice for a beginner.

The only downfall I can find with this wonderful product is that it only comes with one pump. You have to purchase additional units and pair them. Fortunately, the price for these units are very reasonable.

Perfect For – The Beginner On A Budget

4. GHL Doser

The GHL Doser is Germany’s answer to the Neptune DOS. I would argue that this is the best overall doser on this list. It not only comes with 4 dosing heads, but it comes with it’s own controller that is WiFi enabled. The app itself is easy to use and the pumps are powerful. They can push and pull liquids up to 50 feet in length, giving you a lot of flexibility on where you place this pump.

You can add an additional slave unit to this dosing pump for a total of 8 pump heads all controlled by the mobile app. It has one of the most accurate and reliable doing motors and each pump can be calibrated individually.

So what keeps it off from my editor’s choice badge? Its the price. It is very expensive, almost double the price of most other dosing pumps available. It tends to be out of the range for most hobbyists. It is worth the investment if you can afford it. It’s the most accurate and reliable dosing pump money can buy.

Amazing for – Those Looking For The Best Money Can Buy

5. EcoTech Versa

The EcoTech Versa is Ecotech’s Answer to the GHL Dosing Pump. It is a perisaltic pump that is designed to run off Ecotech’s Mobius app. As we have seen in my reef led review post, the mobius app is well designed and easy to use. The dosing pump offers three modes of dosing with automated, continuous, or manual.

This is a great pump solution if you are already running EcoTech equipment since mobius can run everything for you in the app. The pump system also has nearly limitless expansion. The app will allow you to run 200 versa pumps per system. That number is just unheard of – not even an aquarium controller solution can pull that off! This pump is definitely for the hardcore reefer with multiple tanks or the frag grower.

The price to start isn’t that bad either for a premium solution. Because you can purchase these on a per unit basis, you can start with two to get you started on a two part dosing solution and still be under $300. Given the brand name and quality, that’s not a bad place to start.

For – Those Looking A High-End Solution They Can Growth Into

6. Kamoer Peristaltic WiFI

Peristaltic pumps are very popular for advanced reefers and also in the medical industry¹. Their biggest selling point is their ability to change flow rates while they are running. They are designed to run constantly.

This new version model works off a WIFI app, which means it user friendly and easy to use. These pumps work really well with calcium reactors. One of the biggest issues with calcium reactors is frequent adjustments. You will save a bunch of time switching to this solution over other pumps like the Tom Aquatics dosing pumps. Just set it and relax.

It comes with a heft price tag, but if you are running a calcium reactor, it’s a great choice.

Perfect For – Those Wanting An Accurate Device or Using A Calcium Reactor

7. Jebao Programmable Auto Device

The Jebao Dosing Pump is usually what reefers on a budget go for when they looking for cheap dosing pump to get them started. I saved this product for last on my list. You may be wondering why. After all, it has four dosing pumps and has a great price!

The main thing is that they have a history of bad quality control. Quality can vary when you order an import product and for something like a dosing pump, I would prefer to stick to higher quality brand. I feel the Kamoer X1 is a better buy and easier to use.

If you are looking for cheap and multiple pump heads, this can be the solution for you. Just make sure you calibrate the pump consistently.

Amazing For – Those Looking For A Cheap Option

What Kind Of Tanks Will Benefit from This?

The best aquariums for a dosing pump would be reef tanks that have a heavy need for calcium and alkalinity. These would be aquariums that are dominated by LPS and SPS corals. They are also beneficial for tanks that run on low nutrients. This is a more common issue with modern reef tanks. They often run low on phosphates and nitrates and need to be dosed into other to keep them at stable levels.

Another good aquarium to use a dosing pump for would be high end planted tanks. You can use a dosing pump to automate your micro and macro nutrient dosing and keep your planted tank stable

Which One Is Right For Me? ( My Recommendation)

The best aquarium dosing pump to buy would the the following three:

• Neptune DOS – The best overall pump and works directly with the Neptune APEX
• Bubble Magus – The best value in dosing pumps. Reliable and easy to use
• Kamoer X1 – The more budget friendly way when it comes to purchasing a dosing pump

An aquarium heater might seem like a boring purchase, but I’ve seen more fish deaths caused by heater failures than almost anything else. A heater that sticks on can cook your fish overnight; one that fails in winter can crash the tank before you notice. Over 25 years I’ve tested more heaters than I’d like to admit, and I’ve narrowed down what actually matters — accuracy, reliability, and safety shutoffs. These 11 are the ones I’d actually trust in my own tanks.

Are you struggling with finding a quality aquarium heater?

In this blog, we share the best products for aquarium heating, from submersible heaters to inline heaters. I also include aquarium controllers in the mix.

With over 25 years of experience in the aquarium hobby, I’ve assisted countless clients, hobbyists, and readers like you in overcoming their heater woes (and believe me, heaters are a headache with how often they fail). I’ve personally tested these products in real world scenarios to determine the best aquarium heater on the market. Check out our YouTube video below:

The Top Picks

I’m going to discuss multiple types of aquarium heaters at this point. But for those in a hurry, here is a quick view of the top 3 three. The answer may surprise you.

The best bang for the buck for those who are only able to purchase a single heater would be the Eheim Jager Aquarium Thermostat Heater. If you have medium to large setup, I would recommend the Finnex STE or go up to the Helio Heater if you have a lot invested in a tank (e.g. – a reef tank).

The Candidates – A Quick Comparison

There are many aquarium heaters out on the market for various tank size options out there. The list below was handpicked by our years of experience in the hobby and through various client builds. They all have their strengths in particular setups which I will explain below. This post will primarily focus on my aquarium heater reviews for the best fully submersible heater types.

The Best Aquarium Heaters – 11 Best For 2023

Let’s go into the details and see why each fish tank heater made the cut.

1. Finnex STE Titanium Series

I’ll say it now and I’ll say it later in this post, aquarium heaters as a whole are generally prone to failure and highly unreliable. We as hobbyists, have struggled for years waiting for someone in the market to develop a heater that could be reliable and not destroy our bank account in the process. We finally have a player in the market who has finally delivered that reliable heating unit we have been waiting for.

The Finnex team at has developed the holy grail, a Controller with Japanese components and a advanced electronic heater element that rids us of all the nightmares of heater failure. What are the factors that scare us as aquarists with fish tank heaters? They are:

• My heater gets stuck in the on position and fries my tropical fish
• My heater cracks and explodes, which kills my fish
• A large fish smacks my heater and cracks it
• My glass heater is made of cheap glass that breaks over time from the heat stress

The Finnex team gave me the honor of providing me with a free heater so I could put in my friend Ryan’s tank. I have a video about the entire video below from our YouTube channel.

Here is what I love about this heater:

• It’s Japanese made. I know how well Japanese made products are from the team at Tunze and ADA in the aquarium industry
• It is accurate up to 1 degree – which is a benchmark for any heater controller I use
• The dual circuitry built into the controller gives you a controller in a controller. The redundancy you need to prevent any type of overheating from failure
• The controller is waterproof sealed, a step up from the Inkbird controller
• It is ETL rated

While it is only covered by a 1 year warranty compared to a 3 year from BRS (more on them below), the Finnex STE is significantly cheaper and the controller is better making this is an overall best buy. I am and continue to be a fan of the BRS heater, however, the Finnex is more approachable. At its price point, it is more accessible to the general fishkeeping hobby, especially freshwater tanks, which I know is nearly 4 times bigger than the saltwater hobby.

In our review, Ryan and I did notice a problem with the heater. The heater is only designed to be on 30 minutes at a time. Because of this, my typical 3 watt per gallon rule of thumb doesn’t work here. You will need to size up appropriately. In Ryan’s 60 gallon tank, this required us to size up to the 400 watt package in order to achieve a reliable and stable temperature free of temperature fluctuations. Keep this in mind if you have amp concerns with your breaker or your controller if you use an aquarium controller.

This is the heater setup to purchase if you are looking for a top notch heater that is reasonably priced, won’t fail on you, and a heater that your fish can’t break (since the heater element is made of Titanium).

Pros

• Japanese Components
• Excellent controller with easy set temp features
• Titanium heating element

Cons

• 1 year warranty
• The controller doesn’t have a low and high temperature alarm
• It’s expensive compared to other heaters like the Ehiem

Finnex STE Rating

2. Eheim Jager – Old Faithful with Legendary Brand Name 

Ah the Eheim Jager Aquarium Thermostat. They have been around seemingly forever and completely unchanged for ages, and there is a good reason why. It is simply a very well-built and reliable heating unit for both freshwater and saltwater tanks. Quality German-made, UL-listed electronics, and a manually adjustable heater gauge are its main features. The Jager aquarium thermostat heater has an accurate temperature sensor up to 0.5 degrees Fahrenheit of the desired temperature.

This makes it as accurate as the Cobalt Neo-Therms. It also has the ability to be re-calibrated! I has a thermo safety control which automatically shuts off the heater in the event that the tank runs low on water. The indicator light is also easy to see so you know when its working.

Because it is it a quality manufactured heater, it simply hasn’t been updated in years and looks the part. It is a big and bulky glass tube, it uses old school lab-grade glass, and the adjustable dial itself is cumbersome. However, Eheim’s legendary name brand is behind it and anyone who has been in the aquarium industry knows the great quality and durability that Eheim manufactured products bring. It’s ugly looking and big, but you won’t be disappointed using this as your fish tank heater.

Pros

• German-made and Eheim name
• Accurate up to 0.5 degrees Fahrenheit of set temperature
• Can be re-calibrated

Cons

• Big and bulky submersible heaters
• Old school lab-grade glass design
• The water temp dial is a bit clunky

Eheim Jager Rating

3. Innovative Marine Helio

There comes a time with aquarium technology when a major breakthrough is made. We saw this when aquarium return pumps shifted from AC to DC and when we saw the shift from T5s to LEDs in lighting technology.

We now see the same shift with PTC technology with the Innovative Marine Helio. This heating unit is the first of its kind in the industry. It does not operate like the other heaters on this list that use traditional resistance wires to heater terms. This type of technology is quite old, originating from toasters. That’s right, the same technology used in many aquarium heaters today is no different than what you use to toast your bread!

The problem with this traditional technology is if these fish tank heaters are exposed to air or become covered in debris, they run the risk of overloading, which leads to the explosions and failures many of us experience hobbyists have dealt with in the past.

The Helio changes all of this. The PTC technology uses chips that are programmed to heat at predetermined set temperatures. This results in a safer and more reliable heater. It’s all controlled by the Helio controller. Both the heater and temperature control device were heavily researched by the IM team. They looked at how aquaculture facilities managed their aquarium water temperature. As a result, the Helio is developed like a commercial versus hobbyist grade product.

A new commercial developed product like this demands a very high price. This is the most expensive heater on the list but has the most potential of every heater here. The technology is promising. I see more and more high-end heaters in the future utilizing this technology as it matures, and the price as a result drops as more brands develop it. You will pay a price premium by adopting this technology early.

Pros

• German-made and Innovative Marine name
• Cutting-edge PTC technology
• 5-year warranty

Cons

• Not designed to be used inside display tank
• Very expensive

Helio Rating

4. BRS Titanium Element

The heating element is made of titanium, which is unbreakable in our hobby and can conduct heat better throughout the body than other materials. It is German-made, a standout among a number of heaters that are now being produced in China.

When it comes to hearing and accuracy of this heater, the BRS element has been thoroughly tested and will maintain a temperature deviation of 0.5 degrees or less when equipped with a high-quality controller. This ensures that your tank’s temperature will remain stable and keep your aquatic pets healthy.

Being a titanium heater, the element is more efficient than traditional glass heaters. While it will consume the same base power, the heater is more efficient because the titanium construction will conduct heat better than glass. This will save you on energy costs and reduce the carbon footprint of the heater.

Being made from titanium, these heaters are the ultimate when it comes to durability. They are virtually unbreakable and will take the more extreme punishment from large fish and won’t explode on you. These fish tank heaters have the confidence of the manufacturer to provide a 3-year warranty.

Because of their makeup, they require a controller to adjust the temperature. You can either hook it up to an aquarium controller or use the model offered in the link above that connects to an Inkbird. The Inkbird has been a personal mainstay for me over the years, and I feel great using it with this system.

It’s a pricy heater, but it really is what fish tank owners have been looking for all these years. When you have a tank with hundreds or even thousands of prized tropical fish and corals (or tons of live plants) – you demand a heater that doesn’t fail. The titanium element offers you that peace of mind. It’s a must for anyone with a prized display tank.

Pros

• German Made
• 3-year warranty
• Works with a controller

Cons

• Expensive
• No models for smaller fish tanks
• Inkbird controller isn’t as good as the Finnex STE

BRS Titanium Element Rating

5. Cobalt Aquatic Neo-Therm – The Most Accurate on the Market

If you have a system that requires precise constant water temperature with sensitive inverts, corals, or tropical fish like a reef tank, the Cobalt Aquatics Neo Therm Heater can’t be beaten. Cobalt Aquatics computer tested all their Neo therm heaters. They are accurate up to 0.5 degrees Fahrenheit of the set temperature (better than most controllers on the market in fact), the Aquatics Neo Therm heater, to many in the reef aquarium hobby is the go-to – especially in nano tanks. The Neo-Therm is also one of the most compact heaters. It can fit in any all-in-one aquarium or nano tank and will hide well if placed inside the tank. For overall features, this is the best submersible aquarium heater you can buy today.

It does come with a higher price tag though. The Neo Therm heater is one of the more expensive heaters available and they also only come in smaller wattage sizes, meaning you will need multiple units to run a larger tank.

Pros

• Accurate up to 0.5 degrees Fahrenheit!
• Manual water temperature adjustment dial
• Compact design – fits in all in one system

Cons

• Only available in smaller wattage
• Expensive

Neo-Therm Rating

6. Aqueon Pro Adjustable – With a Limited Lifetime Warranty 

If you are looking for a reliable shatterproof adjustable submersible heater, with a limited lifetime warranty, look no further than the Aqueon Pro Adjustable Heater. Aqueon has been in the Aquarium industry for a long time and many of us have trusted them for our tanks as many of the standard tanks old these days are manufactured either by Aqueon or Marineland.

The Aqueon Pro Adjustable Heater comes with a water temperature dial that is painless to adjust the temperature. Because it’s manual control, it is less prone for its temperature configuration to fail because the setting will not reset during a power outage. The Aqueon Pro is accurate within 1 degree of the desired temperature, which is adequate for most home aquariums, but would be considered suspect in a delicate environment such as a reef tank.

Pros

• Lifetime warranty and Aqueon Name
• Manual water temperature dial that will not reset in a power outage
• Shatterproof design

Cons

• Temperature sensor only accurate up to 1 degree
• No separate controller for redundancy

Aqueon Pro Rating

7. Fluval M-Series

The M-Series is Fluval’s value heater offering and one of the common ones you will see at pet stores and local fish stores. If all the heaters you will find at non-specialized pet stores, this will likely be the best glass heater you will find on the rack. It’s made of Borosilicate glass and backed by a 3-year warranty. Fluval has a big presence in our aquarium industry and many of its products are known for their reliability.

The M-Series is a budget heater. While it is not as high-end as the BRS heater element or as well-built as the Eheim Jager, it is still a competent heater. It’s also smaller and less bulky than the Jager, which makes it more suitable for all-in-one aquarium and smaller tanks.

While heaters are prone to failure, this is still one of the better ones out there. With proper backup protocols, you should be happy with purchasing an M-Series.

Pros

• Good price
• Hagen/Fluval name
• Computer calibrated
• More compact than the Eheim
• The suction cups work well

Cons

• Inferior to the Eheim heater
• Still prone to break from large fish
• No separate controller for redundancy

Fluval M-Series Rating

8. Finnex Deluxe Titanium – Great for Monster Fish Keepers

For those of us with large tanks over 200 gallons, it is difficult to not only find a high wattage heater, but also a heater that is about to take the punishment of large aggressive fish who may thrash about in the aquarium and knock down rocks and equipment.

This is where the Finnex Deluxe Titanium Heaters answer the call. It is a titanium-built heater, which makes them virtually indestructible. A titanium heating element is more corrosive resistant than glass heaters, making it ideal for saltwater environments.

Before I discovered the Inkbird, this was my recommendation for someone who wanted to use titanium heaters. It’s cheaper than the BRS element, though the controller is not as accurate as an APEX or Inkbird.

However, because there is no adjustment dial on the heater itself, there is no redundancy on the submersible heater to protect against failure. The controller itself is only accurate up to 2 degrees Fahrenheit, which is fine for freshwater fish tanks and fish-only saltwater setups. Reef tank users will want to consider purchasing the Finnex Titanium Heater Rod only and go with a more accurate aquarium heater controller or utilize a high-end controller like an Apex Controller.

Pros

• Titanium built design
• Comes with a digital controller
• Available in up to 800W

Cons

• No adjustment dial on submersible heater itself
• Controller is accurate only up to 2 degrees Fahrenheit of set temperature
• Not available in smaller sizes

Finnex Deluxe Rating

9. Finnex Titanium – Titanium for the Rest of Us

Titanium heaters are considered better than glass heaters due to the fact that titanium is more corrosive resistant and is nearly indestructible. Our last heater was only available in high wattage, but this variation of Finnex Titanium Heaters is for the rest of us. With very similar pros and cons, this heater will get you a titanium submersible heater at a reasonable price. It also comes with a heater guard to protect fish from touching it.

Like with most titanium heaters, the heating element does not have a manual adjuster on board. To program to the desired set water temp, you have to use the controller that comes with it.

This heater is one of the most affordable titanium heater solutions out there that is a name brand. It’s cheaper than both the BRS and digital heater. It also comes in smaller sizes, so you can use them in smaller aquariums. Titanium heaters, in general, will use less electricity than glass heaters since they conduct heat better.

Pros

• Titanium built design
• Comes with a digital controller

Cons

• No adjustment dial on the submersible heater itself
• The controller is accurate only up to 2 degrees Fahrenheit

Finnex Titanium Ratings

10. Hydor In-line – A Great Choice For Canister Filter Users

The Hydor Inline Heaters are the perfect choice for aquarists who own a Canister filter. Because this heater runs through your return line, you do not have to worry about this heater being inside of your fish tank and prone to the abuse some of your fish would cause on it moving rock work or even yourself hitting it accidentally performing maintenance.  It is constructed with Hydor’s patented PTC heating technology. The way the unit works is that it is made of a special polymer that has been printed with aquarium-safe ink. This ink heats up the passing current as the water is transferred into your aquarium. It really is a fascinating technology!

When it comes to performance, the Hydor heater is a step up to a submersible heater. The PTC technology is unique and new age. It heats water as it passes through. It is more efficient and provides heating that can remain hidden in the tank

It does come with some major drawbacks though. It must be installed in the vertical position, which can be a problem for those with limited space in their cabinets. It can be only installed with vinyl tubing, making it non-ideal for setups with hard plumbing. It is also only available in up to 300W. You can’t run a second heater inline. However, my personal experience with these heaters is that they do not fail as often as traditional glass heaters.

Hydor also does not state how accurate the heater is on their specs; a controller is highly recommended. It is a great alternative to a submersible aquarium heater.

Pros

• External heater
• Slick operation and patented technology
• No risk of heater burn on fish

Cons

• No specs from Hydor on how accurate it is
• Can only be used with vinyl tubing
• Only available up to 300W

Hydor Rating

11. Hyggar Titanium – New Player on the Market Delivering Budget Items

This aquarium heater really surprised us. The Hyggar Titanium Heaters come with a digital temp controller that claims 0.5 degrees of accuracy. That claim would make it one of the most accurate controllers on the market. I would say from testing this product now that it doesn’t have that stated accuracy, but it is a good budget titanium heater. It is cheaper than the BRS, and Finnex heaters.

Being titanium, it is nearly instructable and is more energy efficient than cheaper glass heaters. It is available in multiple sizes and is compact enough to work in some small tanks.

They were a newer brand in 2023, but the reviews have been pretty stellar, enough for us to consider them on our list for aquarists looking for an all-in-one solution titanium heater with a controller. They have reached out to use for a sponsored video, but we declined as we prefer to keep our reviews independent.

Pros

• Titanium design
• Controller claimed accuracy of 0.5 degrees

Cons

• New manufacturer

Hyggar Titanium Rating

Benefits (Why Do I Need To Purchase One)

Because most of us in the fish keeping hobby keep tropical fish (saltwater fish), they require the water temperature range to be consistently around 75 – 80 degrees Fahrenheit ( 24 to 27 Celsius). Since we keep aquariums indoors in our home, most people would think that the room temperature of our home could keep our aquariums at a safe water temperature. However, seasons change and there are certain times, like in the winter, when the room temperature in your home can drop below 70 degrees or less in your home putting our precious livestock at risk. They don’t handle temperature changes well.

The best aquarium heaters not only keep your water temperature up for your tropical fish but are easily adjustable so you can keep your water at the desired tank temperature. They are also accurate to boot. Some will even come equipped with a separate temperature controller so you add redundancy in the event a heater fails.

What We Looked For

Figuring out the best aquarium heaters on the market is not easy to do. There are lots of manufacturers out there from many different price points. To filter out the good from the bad here is what we used in our criteria.

Manufacturer of Origin

The aquarium industry is loaded with a ton of budget-friendly products, but this also means the quality and reliability of the product could be suspect. It’s very easy to go to places like Amazon and find a cheap Chinese-made heater to work on your tank. However, they typically do not have good quality control and aren’t built to last.

Heater failure is a serious issue in the hobby. I’m looking for German or Italian made and looking for products with big warranties.

Brand Name

Good brands back up their products with warranties and lab tests. Brands like Eheim have stood the test of time and get my vote over budget brands.

Accuracy

A heater should be pinpoint accurate and consistent. The best heaters on the market will be within 1 degree accurate and will be easy to calibrate.

Build Quality

You want a product that has features like auto shutoff if the heater gets too hot or it runs dry. You want a heater that is more durable materials like titanium or lab-grade glass.

All these criteria get a rating of 1 to 10 with 1 being the worst and 10 being the best. We take an average score to determine our best heaters. Note that price doesn’t come into the equation. With the exception of heaters on this list, we don’t feel that price is a major determining factor. With these two products that are pricey, if your livestock is expensive, we feel the purchase is justified.

How to Choose the Right One

I’ve provided a lot of choices here and it can be frustrating to figure out which one works best. No worries though, let me help you out.

Sizes

All the aquarium heaters listed in this blog post come in various sizes. Some like the Eheim Jager Aquarium Thermostat are very bulky while the Cobalt Neo Therm Heaters are very compact in size. If you do not have a sump or canister filter, the size of the heater will come into play as it may stick out like a sore thumb. Smaller heaters are easier to hide and also getting multiple heaters will help with hiding them in the fish tank (redundancy is also another reason to get more than one heater which I’ll explain in further detail).

Types

Aquariums

The type of aquarium you own will help determine what heater you will need. For example, if you have a fish-only freshwater community fish tank with mostly hardy fish, you can likely get by with a single heater and a relatively cheap one.

If you have larger predator fish like Cichlids or Arowanas, you will want a submersible heater that can take a beating. This is where Titanium heaters can come into play as they are virtually indestructible.

For those of us who have sensitive inverts or exotic fish as you may have with a saltwater reef aquarium, the accurate and reliable temperature is critical. A swing in temperature range could cost thousands of dollars in lost livestock with such setups. Therefore, as a reef tank owner, it is imperative that we build our heating system with multiple redundancies and safeguards to protect our livestock.

Heaters

I did throw out a number of terms when it came to fish tank heater construction so I can be a little more detailed here. A submersible aquarium heater will typically be constructed with the following materials:

• Glass
• High-Quality Glass like Quartz or Borosilicate
• Titanium

Glass heaters are what you will typically find with value-based brands that are not listed on this list. I have completely ignored these because they are prone to exploding in a fish tank and shattering! Not something you want:

Highly quality glass like what you see with the Eheim and heaters is durable glass that is resistant to thermal shock and less prone to exploding like above. They can still crack if dropped or hit by a rock, but in normal operation, they should be fine, especially if they are placed in a safe area like a sump.

Titanium heaters like the Finnex heaters are virtually indestructible and great for tanks with larger fish. They also tend to be the most expensive of the lot.

Your Budget

I have listed a number of quality heaters in this post in all ranges of budgets. One thing to note is that many aquariums will run multiple heaters and I am aware that not everyone will have the budget to deploy a multiple heater setup. The heater for bang for the buck I feel is the Eheim heater. Eheim offers a reliable heater with the best mix of quality and price.

Where to Place It

It is the best to place your fish tank heater in an area that gets a good amount of flow. This will normally be an area in close proximity to a power head, power filter, or air stone. You also want to keep aesthetics in mind so if you are placing the heater directly into your display, you will want to place the heater behind rock work or plants.

Placement is even easier with an all-in-one aquarium as there are compartments available in the return section where you can place your submersible aquarium heater in. If you have a sump, it’s even easier can you can place them in your sump after your first chamber.

Fish Tank Sizes	Heater Wattage Needed
10 G	30 Watts
20G	60 Watts
29G	87 Watts
40G	120 Watts
55G	165 Watts
75G	225 Watts
90G	270 Watts
125G	375 Watts
180G	540 Watts
225G	675 Watts
300G	900 Watts

How To Fool Proof Against Failure

As I stated when I talked about the BRS heater element, aquarium heaters, unfortunately are prone to a number of failures. These failure points are:

• The aquarium heater explodes
• The aquarium heater cracks
• The aquarium heater’s internal thermometer fails
• The aquarium heater’s off/on mechanism fails
• The aquarium heater’s settings reset after a power outage

That is A LOT of failure points. It’s also a bit scary to know that the #1 tank crash reason are aquarium heater failures. It’s not a disease, it’s not a power outage, but your heater failing. That’s correct, a measly $30 heater can be the cause of you losing hundreds of dollars of fish and pets that you have owned and cherished for many years.

This is why we recommend purchasing an aquarium heater system. This would encompass:

• The best fish tank heater from this list
• Running two heaters instead of one that gets to the recommended wattage level
• A separate aquarium controller that is accurate at least to 1 degree Fahrenheit and can run both heating and cooling equipment
• A reasonable piece of cooling equipment that won’t break the bank

Since I know a number of my readers cannot afford or do not want to pay for the premium of the BRS heater element or Helios, this section of this blog post is to help guide you on setting up a reliable heating system for less money.

Get A Good One To Start

I mentioned it early on in the post what my top 3 are. I would stick with those as you can’t go wrong with either. All those heaters met my strict criteria and receive my full recommendation.

Failsafe #1 – Running Two Instead of One

Why would we run two heaters? Well, as I mentioned, heaters have many fail points and one of them is the off mechanism failing. This will mean that the heater will stay on and effectively cook your tank. This is the #1 reason for a heater fail. When you purchase two smaller heaters, if one fails at the on position it is not powerful enough to cook your tank inhabitants. It will stay on and you should have ample warning to notice the failure and act accordingly.

Failsafe #2 – Running a Separate Controller

Since running two heaters will give you time to act in the event one fails at the on position, you could be out of town or not present for some time to act. This is where a separate aquarium controller comes in. A separate aquarium controller has it’s own temperature sensors or probe and mechanics separate from an aquarium heater. This provides you with an additional fail safe. Now both heaters AND the controller would need to fail at the same time in order for your tank to experience a crash. That is very unlikely to happen.

The Controllers

So now let’s talk about aquarium heater controllers. The controllers from Finnex and Hyggar are pretty good, but the Finnex controller is only accurate up to 2 degrees and the Hyggar controllers are new to the market. There is one heater controller that has been around for a while and is trusted in other industries aside from the Aquatic industry – namely aquaponics, and beer brewing.

The Inkbird Aquarium Controller – The Best Bang for Buck Controller on the Market

I know there will be some folks on the comment section who may post and say that I should talk about aquarium controllers, but to me, that is a completely separate subject. Aquarium controllers are very expensive and even an entry-level controller is going to cost over $200, which is going to be out of the range of many readers of this post.

The inbird is a great budget controller with a large LED display. The Inkbird ITC-308 is a great aquarium heater controller that is accurate up to 1-degree Fahrenheit. It is easy to program and has the ability to not only control heaters but cooling equipment as well. This actually provides a TRIPLE FAIL SAFE as the cooling function will kick off in the event the aquarium gets too warm. If the aquarium gets too hot or cold, the Inkbird can sound an alarm letting you know something is wrong. There is also a wi-fi version available so you can get temperature alerts on your phone if the fish tank gets too warm or too cold!

HYDROS Control 2 – An Entry Level Controller

The Hydros Control 2 is a step up from the Inkbird. It has the wifi features and more. It can control temperature and a number of devices, detect leaks, and more. It was developed to be a cheaper alternative to the Neptune APEX and a worthy successor to the Reefkeeper entry-level controller.

This controller provides even better assurance that your temperatures stay stable. I typically go with an inkbird on smaller budget builds, but if I have more budget and my client isn’t looking to get an APEX, this is a definite consideration for me. If you are looking for a compete solution, I would recommend looking into my best aquarium controller post for details about controllers that are able to automate multiple aquarium functions.

The Cooling Fan – The Final Fail Safe

Since these aquarium heater controllers have the ability to cool down a tank, let’s get a reasonable piece of cooling equipment. An aquarium chiller is going to be out of the budget range of many aquarists so a cooling fan is a good option for us to look into.

The IPETTITE Aquarium Cooling Fan is a very reasonable piece of equipment when teamed with an aquarium heater controller can provide some cooling in the event your tank gets too warm. It’s not a chiller, but it should get you by in most situations. If you need to take it to another level, you can try looking at my best aquarium chiller post for options regarding chillers.

Final Solution – Incorporate Replacement In Your Maintenance Cost

Replacing your heater every year has become a trendy strategy, especially for those who keep expensive setups like reef tanks or aquascapes. When you have invested thousands into a setup, it’s not a big deal in the grand scheme of things to budget $60 a year to replace your heater annually. If you have a setup this expensive, I would recommend this approach but still stick to higher quality heaters. Jagers are a great choice for this method as they are fairly inexpensive to replace. The heating element for the Finnex STE is also reasonably inexpensive to replace.

FAQS

Wrapping It All Up

Well, this was a pretty long post. I hope I was able to provide you with the information you need to make the best-informed purchase. As I stated earlier, there is a reason for these aquarium heaters to be on our best-of lists as they all have their place depending on your aquarium situation and budget.

If you have any questions, please leave a comment in the comment section. If you have a fish tank heater you feel is the best, drop your thoughts below. Thanks for reading :).

Having your aquarium run automatically is a dream for many fish tank owners. Everyone wants a device that can automate many of the mandate tasks of fish and coral keeping. What if I told you that such devices exist today? They in fact do exist, and many do an excellent job of making your aquarium keeping life easier than ever before! They are called aquarium controllers and the technology is now over 10 years old. But what is the Best Aquarium Controller? There are a number in the market now, and they require a lot of research and development to create a long-standing product.

In today’s post, I look at the best of the best and tell you which ones are the ones to purchase today. So let’s get started and see what the marketplace offers. You will be excited to see what these things can do now!

What To Look For When Buying An Aquarium Controller

Before we start comparing aquarium controllers, we need to talk about what to look for when purchasing one. Controllers are a complex technology and not every company can maintain the product line in the long run.

A controller is a premium piece of aquarium equipment. It is one of the most expensive devices you can purchase for your tank and for very good reason. They are capable of automating many tasks in your tank.

For these controllers I’m reviewing today, this is my criteria:

• Quality
• Features and Accessories
• Brand Name
• Price

The Candidates

Now that we know the criteria I’m looking at, let’s see who makes the cut. The list below are the picks I would be proud to put into my tank setups. They are offered by high quality manufacturers who have been around for years. There is no up and coming venture backed company here. These are all high quality name brand controllers. Let’s continue further below.

In a hurry? I recommend the Neptune Apex!

The 8 Best Aquarium Controllers – 2023 Reviews

Let’s see what these made the cut!

1. Neptune Apex

The Neptune APEX was the original aquarium controller released in the United States and continues to be to this day the best controller on the market. What makes it stand out is its ability to integrate with nearly all modern reef keeping equipment today. Every high end manufacturer wants to market as an “APEX Ready” or APEX capable controller. Not having this feature puts them at risk of losing a large amount of sales. This type of brand name recognition makes the APEX the premier controller and the go to for modern tank automation.

The APEX package comes with four probes out of the box – temperature, salinity, ORP, and pH. The salinity probe is the biggest selling point of this set. A salinity monitor is usually a separate purchase – and it isn’t a cheap add-on. These probes are lab grade and have a longer lifespan due to their double junction construction.

The new APEX model runs off wi-fi, eliminating the need to have your controller plugged into a laptop to access. You can run it on your desktop, laptop, tablet, even on your phone while you are away from your tank. It is total piece of mind when you can monitor many parameters while you are away. You can even have a maintenance profession log into your console and see your setups.

The energy bar 8 is an ETL certified power block that holds up to 8 devices. Each outlet has independent monitoring to your console. Each outlet is measure for voltage, which is a key parameter to measure when it comes to equipment. Low output could point to upcoming equipment failure and an early warning sign to replace equipment.

And this is all just talking about what comes in the box! The APEX has a number of add-ons you can bolt onto the system. Such add-ons include a leak detection kit, dosing automation, flow monitoring, an ATO line, PAR monitoring, and automatic fish feeders. The most recent add-on, the Trident, promising complete dosing automation. This is the holy grail of reef automation. It really is a complete aquarium monitoring system.

The future is bright with the APEX Neptune. It is a solid investment that comes with you with any aquarium you keep and can even be used to run multiple tanks. The biggest downfall is its price. If you are running an aquarium with prized exotic livestock and corals, the price actually doesn’t seem that bad compared to the value that is housed in the tank.

Pros & Cons

2. Neptune ApexEL – A Budget Apex

The biggest issue with the APEX Neptune is the price. This Neptune ApexEL line is Neptune’s answer for a budget friendly aquarium monitoring system. The APEX EL still has the same great tech with the wifi capability, energy bar 8 hub, and the ability to add all the major Apex add-ons.

What’s missing from the EL model? It’s three main things:

• The APEX EL does not have a salinity probe
• The console hub is missing a 0-10v port which doesn’t it allow it to connect with devices like Kessils and Varios pumps
• The APEX EL does not have an ORP port or probe

All three missing items can be added back with add-ons if you chose to purchase them. I feel what is missing is a good sacrfice compared to what is included. The salinity probe, while great to have isn’t completely necessary and is also new technology to the hobby. The missing ports are only a factor if you purchase Kessils. Finally, many reefer tank owners don’t even bother with ORP monitoring, so a missing ORP probe is not a deal breaker.

This is a great alternative model to the main APEX model. The price can still be too expensive to some. For the price it sells out, there is a lot of value. If you want something cheaper, I have a great option below at #3.

Pros & Cons

3. Hydros Control 2 – A Modern ReefKeeper Lite

If you reefed in the early mid 2000s, you were treated to this wonderful early level controller called the ReefKeeper Lite. It was praised across the hobby as the bang for the buck controller that would one day save your tank from an aquarium heater malfunction with its temperature controller. It provided the most essential pieces of tank automation to you with its 4 outlet power block. However, the company that created the ReefKeeper Lite – Digital Aquatics, went out of business in 2018. Ever since then the hobby has been search for the next ReefKeeper Lite in a world that was dominated by high end controllers like the Neptune Controller.

Enter the new kid on the block – the Hydros Control 2 kit. This is CoralVue’s answer to the demand of the return of our beloved ReefKeeper controller. Now with the backing of a major manufacturer like CoralVue, the Hydros as the ability and capability to provide what we love out of the APEX without the crazy APEX price.

This Control 2 model is the closest match you will find to the old ReefKeepers. With this package you get

• A 4 outlet power supply
• Temperature probe
• WiFi capacbility
• Hydros Control App

The Control App is a great step up to what we are used to seeing with the Reefkeeper which was just a simple interface with buttons. The control runs off a mobile app. It allows you to program the controller without coding knowledge. One of the biggest frustrations with high end controllers is they are too complex to use for newcomers. The Hydros app is user friendly

The price of this controller is more expensive then the original Reefkeeper Lite, however, the value they provide is greater. The price for these I still feel is entry level and a solid investment. The sensor ports currently support optical sensors, leak detectors, water level sensors, flow rate sensors, and switches. This package has incredible value and my #1 pick when it comes to the best budget option for a controller.

Pros & Cons

4. GHL ProfiLux – Germany’s Answer to the Neptune Apex

The GHL ProfiLux is Europe’s version of the Neptune Apex. It is German made and has quickly grabbed market share away from Neptune as Reefers have realized how reliable and durable these controllers are. The controller is globally recognized for its accuracy and reliability, being used in research institutions and public aquariums.

Aside from the global recognition of the controller, what else makes this controller stand out from the APEX? In short sum, here are the main points:

• The GHL has future proof internal boards that are replaceable and upgradeable
• Better detailed control of lighting, temp, pH levels, pumps, etc
• Easier to program through their logic gate programming
• Simple yet more durable build quality

One of the biggest selling points from the GHL controller is how long they last. You will find owners in the community who have been running the same GHL controller for 10 years. They run the older models, not needing to upgrade to the newest model because GHL continues to support the older models with firmware updates. Try to find someone who is still using one of the original APEX models. You will be hard-pressed. Some have failed over time while others have just wanted the latest and greatest.

German and Italian made products are of the highest quality in the aquarium industry and have been so for many years. It shows again in this controller. It doesn’t beat out the APEX on this round up because of its lack of presence in the United States. Most manufacturers shot for being APEX ready and don’t market to other controllers. It’s also harder to find other aquarists who use these controllers. It’s a niche user base, though a very loyal and happy one. If you want one, be prepared to pay slightly more than you would for the APEX. However, you can expect your controller to last for many years.

Pros & Cons

5. Neptune Trident – True Dosing Automation Is Here

The Neptune Trident when it was announced created a huge buzz around it. It is a game changer for reef aquariums. This is a Dosing controller that attempts to completely automate dosing and monitor the big 3 parameters of coral reef keeping – alkalinity, calcium, and magnesium. Stability is everything when it comes to a reef tank, especially when you get into more advanced corals like SPS.

It works by testing your water multiple times a day then adjusting the dosing schedule based on the results. It uses regents in order to test your water. It takes away all the work of having to test your water every week and tests with excellent precision giving accurate readings to the following:

• Alkalinity: + or – .05 DKH
• Calcium: + or – 15 PPM
• Magnesium: + or – 15 PPM

The Trident interface will also let you know the parameter tests and how much regent you have left. Your reef tank will be its more stable ever with one of these installed in your system.

The main drawback is its price. The regents also add up in monthly costs. This is the benchmark for doing automation today and well worth the investment

Pros & Cons

6. GHL KH Director – An Excellent Trident Alternative

The GHL KH Director is GHL’s answer to the Neptune trident. It focuses on the primary reef tank parameter monitor for corals – Alkanity. Changes in Alkanity also affect Calcium, so have a device that focuses on Alkanity will also work with keeping Calcium stable as well as pH.

The KH Director works with Lab-grade accuracy. It can work standalone with a GHL Doser 2 or can work with the ProfiLux controller. I really like how GHL has this flexibility since not everyone wants to get a controller. The GHL Doser 2 is also one of the best and accurate dosers on the market so pairing them together is a solid choice.

The regents also last much longer than the Trident. A regent will last you up to 3 months while the Tridents only last 1 month and require multiple types of regents. This gives you cheaper ongoing costs over the Trident. It won’t test all the core reef parameters like the Neptune does, but I feel the KH Director is one of the best dosing automation controllers on the market.

Pros & Cons

7. Aqua Logic

The Aqua Logic Temperature controller makes the list as the premier controller for aquarium heater malfunctional prevention. It only does one job, and it does that job very well.

Because it only does only function, it is simple to use and easy to install in your system. These are extremely reliable controllers that will last a lifetime. They are not prone to glitches or errors in software because they are based on tried and true technology that originates in the HVAC industry¹. It is a commercial level device that has been implemented into home aquarium usage.

The big con with this product is that it only does one function. Most controllers these days offer temperature controllers as part of their package. It is also expensive for what it does. The link on this product is the single stage controller. The dual stage temperature controller is a more expensive offering.

Pros & Cons

8. American Marine Pinpoint pH

The American Marine Pinpoint pH controller is a standalone controller designed to work with equipment like calcium reactors and CO2 regulators. It is accurate within .01 resolution with its lab grade pH probe. They are extremely durable controllers that are designed to work for a lifetime.

They will shut down equipment if the pH goes out of range and are easy to use and calibrate. They are excellent for what they are designed for and plug and play.

The main downfall is they are designed for one purpose. They lack the functionality of what modern controller can do. However, these are extremely reliable controllers and if you have one thing you want to monitor like a Calcium reactor or planted tank, this is a great deal for a product that is known to last for many years.

Pros & Cons

Our Expert Editor’s Choice

The Neptune continues to be the best overall brand when it comes to aquarium controllers. I highly recommended the Neptune Apex for those looking for full aquarium automation at the highest level. The Neptune ApexEL is a cheaper alternative for those wanting to build up to a premium system over time. The Hydros Control 2 is a new entry level controller which I feel is a reincarnation of the Reefkeeper Lite. It will do everything that budget controller used to do and more!

Benefits of a Monitoring System

A controller can have many benefits to your aquarium. The biggest benefit is peace of mind and automation. Many of the controllers I have featured here have reporting dashboards that can be loaded on your smartphone, tablet, or PC. They allow you to monitor many aspects of your tank. If something breaks, the controller will know. If something is not operating correctly, you will usually know from the voltage readers on the Neptune Apex.

Regarding automation, controllers have come a long way. The biggest need from a controller is temperature automation, as many of the heaters these days are not high quality and a proper monitoring system is required to keep your tank safe. Controllers can also control your reef light, know when you turn on your aquarium chiller, keep your pH stable, monitor your aquarium wavemakers, and automate your dosing schedule and parameter testing.

The other great benefit is anyone can see your parameters if you grant them access. This is a huge perk if you have a maintenance company working on your aquarium. Some higher end maintenance companies will require you to have a controller for big setups so they can monitor and tweek your tank settings as necessary.

When used correctly, aquarium controllers can offer a ton of peace of mind and save you from an expensive tank crash. They are stellar investments to protect your prized aquatic pets.

FAQs

Closing Thoughts

Controllers are really amazing pieces of equipment. They have made our maintenance lives so much better and I look forward to see more advances with the technology as it matures. I hope you enjoyed this article and it helps you make an informed decision. If you have any questions, please leave a comment below. See ya next time :).

Are you struggling with finding a quality aquarium sump or refugium?

In this blog, we share the best aquarium sump and refugium offerings, from Triton style sumps to 4 stage sumps. Even DIY kits are included.

With over 25 years of experience in the aquarium hobby, I’ve assisted countless clients, hobbyists, and readers like you determining their filter needs and also built a few sumps myself for a 40G breeding and 125 G reef tank. I’ve personally tested these products in real world scenarios to determine the best aquarium sump and refugium on the market.

The Top Picks

There are a lot of options presented in this post so you may be wondering what we would recommend. If you are longer for a sump that has everything, I would strongly recommend the Trigger Systems Triton Sumps. The triton is the go to method for premium reefs today and they offer massive value for those in that price range.

For the budget conscious aquarist, I would recommend the DIY sump and refugium kit by Fiji Cube and pair it with a match dollar per gallon tank at Petco or Pet Smart. You can built a great sump and save quite a bit of money over purchasing a manufactured sump. Sometimes the best aquarium sump is the one you design.

The Trigger Systems Crystal is a great all around package and has a great name behind it.

The Candidates

With all that said, let’s dive in and look at the best aquarium sumps and refugiums available for purchase today. These are the offerings we feature in this post and ones we tested out.

The Reviews (2023 Update)

Now that you have seen the list, let us dive in and see what these sumps are all about!

1. Trigger Systems Triton

The Trigger Systems Triton Sumps are a new concept in sump systems. Sumps first started with Berlin sumps, which was just a sump that had a chamber for a protein skimmer. Then you had the creation of refugium sumps with the skimmer in the first chamber than a small refugium chamber. These were primarily designed for a reef tank to house beneficial organisms. The Triton method is a new reefing method that relies on a larger refugium chamber where the primary filtration method is from the natural filtration of your refugium.

The Triton sump by Trigger systems delivers on the method. It is feature loaded with probe holders, three drains, and adjustable baffles. The refugium section is oversized to accommodate the needs of the triton method. Trigger is well known for making quality sumps in the reefing screen. This is Trigger systems high end reef sump offering.

Pros

• Brand name
• Quality construction
• Modern filtration method for today’s reefs

Cons

• Expensive
• Only one color

2. Trigger Systems Crystal

The Trigger Systems Crystal Sumps is a reasonably priced 3 stage sump that everything you need to build out an elite level setup. It comes with two drains to connect your plumbing and comes with a bubble trap to ensure your return pump doesn’t pull our microbubbles. The bubble trap area can actually house media with their included media platforms. This is an added plus as it puts the chemical filtration in the back versus the front.

The filter sock holder is a locking style that keeps filter socks secure and accepts standard 4″ 100 micro socks. Each drain comes with a bulk head at allows you to insert PVC plumbing into it.

It is a very lean design with a eurobrace to ensure it stays study. This series comes in various sizes, so you can find one that fits in your aquarium stand. It doesn’t have adjustable baffles or probe holders like the Triton to keep costs down. It doesn’t have probe holders, but then can be added easily with accessories in the future

Pros

• Reasonable price
• Has everything you need to get started
• Brand name

Cons

• Still expensive for some
• No probe holders

3. Fiji Cube Kit – A Great Do It Yourself Kit

I am a big fan of building your own sump, especially if you want to incorporate a sump and refugium in your sump as many sump makers do not have chambers for both. This DIY sump and refugium kit by Fiji Cube really answers the call with a high quality sump kit.

The dollar per gallon sales from PetSmart and Petco offer a great way to get a cheap sump and Fiji Cube’s kits are meant for either a 20 gallon or 40 gallon aquarium. This 40 gallon gallon kit will handle all medium sized aquariums and is easily adjustable to either be setup as a traditional sump + fuge setup or as a triton setup.

I really love the three filter sock design, I just wish they would do 55 gallon and 75 gallon sump kits. Fortunately, there is a nice 55 gallon triton sump kit available from Jax.Racks for those of you with 6 foot long tanks.

Pros

• DIY Kit allows you to build the best sump setup for your tank
• Can be setup for either standard Skimmer + Fuge or Triton method
• Kit + dollar per gallon tank = cheap and great value!

Cons

• No drain bulkheads do you need to DIY the drain area to fit
• Only 20 and 40 gallon aquarium kits available
• You need to assemble the kit yourself

4. IceCap – With Auto Top Off Reservoirs Built-In

The IceCap sumps are a well designed sump that include a fresh water reservoir so you do not have to maintain a separate reservoir for top off. This sump has dual drains allowing for a bean animal overflow to be connected to it and the covers most for a very clean and professional looking sump. The sump comes with probe holders and the ability to adjust the water level from 5-9 inches.

This is a great reef sump if you are working with a tight space, or just want a sump with the reservoir built in. The measurement lines on the reservoir is extra helping in determining how much water you have left in the reservoir.

My only critique on this design is the reservoir sacrifices the ability to hold a refugium. I would have preferred a refugium section over the reservoir myself. Fortunately, their larger IceCap XL Sump models actually do have a refugium section AND a reservoir, making the models a comprehensive package.

Pros

• Dual drains so bean animal overflow can be connected to it
• Has a freshwater reservoir so you do not have to have a separate one
• Clean and professional looking

Cons

• Non XL models do not have a refugium section
• Refugium is still a little small on the XL models

5. Trigger Systems Ruby – The Brand Name In These Products

Trigger Systems really started the cool looking sump craze and has been recognized in the industry for their high quality craftsmanship. This Trigger Systems Ruby Sump offers a true 3 chamber sump. Both the protein skimmer and refugium sections are adequately sized to house both comfortably. It has dual drains like most of the premium sumps we have reviewed here.

The filter sock holders lock into place so you don’t have to worry about them accidentally falling into your sump. Three probe holders are included in the first chamber and a media chamber is included so you can place carbon before the return section. The design is finished off by a clean red colored euro-braced design. It really is a competent and well rounded design.

Pros

• Recognized name brand in the industry
• Great all around design
• Nice aesthetics

Cons

• Fuge still could be larger, but Trigger does sell Triton sumps
• Can be on the more expensive side compared to others listed here

6. EShopps Advanced Series – For the Serious Hobbyist

The Eshopps Advanced Series Sumps is the 3rd generation advanced series sump from Eshopps. It is a well built sump that incorporates a skimmer and refugium section. What I love about this sump is that it has a two channel design so as one drain goes to the sump while the other goes to the skimmer. This allows for you to have separate drain flows to your skimmer and fuge section. It comes complete with probe holders and a float valve holder. It is a great all round design.

Because it has two drains on it, it is designed for bean animal overflows. It has a very generous protein skimmer section, which will allow you to add an oversized skimmer. The fuge section is smaller than I would like, but is adequate for this design as it a primarily skimmer run sump so you are definitely going to want to add the best protein skimmer you can afford on this build.

Pros

• Two drains so you can use a bean animal overflow
• Very generous protein skimmer section
• Is built to use a protein skimmer and refugium

Cons

• Models only go up to 36″ in length
• Refugium section is not that large

7. Fiji Cube Pro – A Pro Level Reef Unit

When I first saw Fiji Cube’s Sumps, I immediately feel in love. This is such a clean looking sump and expertly designed. The blue and white design will look great in your cabinet or fish room and they make longer sumps that the other manufacturers do not make.

Let’s talk about why this sump is so awesome. First is the computer laser cut design. Next is verstalie first chamber than can either hold filter socks or be converted to hold media. The skimmer section is just right, and features a tighter fit so there is less wasted space in the sump. The sump comes with probe holders and all baffles can be adjusted. The water level is adjustable to 12″ – which is the highest level available for sumps on this list and all chambers can be adjusted. I love the extra fit features like the removable lids on every section. It keeps things clean of salt creep and enclosed for less water evaporation and humidity in your cabinet.

It is a pricy sump given it’s features. If you are looking for that “cool” sump for your setup, this is one of the best ones to purchase.

Pros

• Design
• Lots of sizes – up to 46″ long
• All baffles are adjustable

Cons

• Pricey

8. Bubblefin DIY – A Cheap Option

The Bubblefin DIY Kit is how to get a DIY done on the cheap. It comes with the acryclic baffles to get your started. You can build your sump configuration however you want with this kit. All you need is silicon and a steady hand when placing the baffles. It’s a completely bare bones kit with just baffles, but a lot of DIYers like this option because they can build whatever they want.

The price of this kit is so affordable, you would have a hard time coming up with something comparable in time and money going to the hardware store and purchasing glass or acrylic baffles.

The only complaint I have from this kit is it is missing a pipe hold or bulkhead. You can purchase those separate from other vendors online though. It doesn’t have the same features as the Fiji Cube kit, but the price is very hard to beat

Pros

• Very cheap!
• Configure your sump like you want

Cons

• Missing filter sock holders and bulkheads

9. Eshopps RS Series – A Great Entry Level Unit

This is the budget offering from Eshopps. The Eshopps RS Series Sumps is most common aquarium sump you will see at local fish stores.

It is a very basic, no frills sump that gets the job done for those who are starting out or just want a very basic sump. They are best meant for protein skimmer powered Berlin style saltwater aquarium and reef tank setups.

Pros

• Simple
• Cheap
• Easy to Setup

Cons

• Single drain means you cannot setup a bean animal overflow
• Can only accommodate a protein skimmer
• Not pretty to look at

What Is An Aquarium Sump?

An aquarium sump is a separate aquarium that is plumbed into your main aquarium. They are frequently used in saltwater aquariums and considered the best aquarium filter option. This is because most of the best equipment available is meant to be placed in a sump. The sump is normally placed inside the tank cabinet and other times they are pump to a separate fish room or basement. A separate fish room or basement offers the most accessibility, but mostly common on larger or commercial builds.

Most of us who will setup a sump are usually going to place the sump inside the cabinet and use a submersible return pump to move water back to the display tank. You can see how a sump is used in a professional environment like Tidal Gardens below:

Most sumps will be designed with 3 sections:

• The drain section
• The flex space section
• The return section

The drain section will usually have mechanical filtration either through filter rocks or filter cups that will have sponges or floss with chemical media. In most saltwater setups, this is where you would install the best protein skimmer that works for your setup..

The flex space section is a section where the a refugium (or fuge for short) would be spaced. Sometimes live or dry rock is placed here along with macroalgae to support microfauna and to remove excessive nitrates and phosphates from the aquarium. In a freshwater setup, this section can be used as a safe place to put freshwater plants like Anubias, Java Fern, Duck Weed, Guppy Grass, Java Moss, and Luffy Marimo Moss Balls are all excellent candidates for a freshwater refugium.

In reef tanks, there is a new method called the Triton Method that switches the order of the refugium and protein skimmer. The refugium is placed first and the skimmer follows it.

The also section is the return section, which is where your return pump goes and where your auto top off is placed. This return section is the part of the sump that will have a variable water level so as your water evaporates the water in this section will drop. This will also be the first area of your sump that will fill up if your return pump is shut off.

What Is A Refugium?

A refugium is a section in your sump that is reserved as a safe space for micro fauna and macro algae in your aquarium in saltwater tanks and a safe spot for live plants in a freshwater tank. The advantages of a refugium are several:

• In a saltwater aquarium, this allows you to cultivate beneficial pods that your fish and corals will in turn eat. The pods also act as a clean up crew that eats detritus in the aquarium.
• Macro algae and live/dry rock can be used in a refugium to house pods and filter out excessive nitrates and phosphates in the aquarium. A large enough refugium in combination with a quality protein skimmer can potentially eliminate water changes.
• For freshwater tanks, plants can be housed here to act as a filtration device to filter out chemicals and excessive phosphates and nitrates. while not as effective as in saltwater aquariums, they are still useful when a large enough refugium is used.

How To Select An Aquarium Sump and Refugium (Buying Guide)

There are A LOT of sumps and refugium designs to chose from. It is pretty overwhelming to figure out what will work best for you. Here are a few factors to consider to help you out:

• Size – You are limited to the size of your cabinet. The bigger the sump the better if you can fit and manage it.
• Versatility – Sump designs with multiple chambers and adjustable baffles allow you to work around the design to fit a variety of equipment.
• Durability – You want your sump to last the life of the tank. It is a pain to replace a size. Consider the following:
  • Acrylic vs. Glass – Acrylic is light and less prone to cracking. Scratching is not as big of a deal with sumps as they are in your display
  • Acrylic vs. PVC – PVC is an even more durable sump design, but very expensive. You can consider a PVC Hybrid that combines both PVC and Acrylic at a lower cost or chose to go all PVC. Either way, the build will likely be a custom aquarium sump
• Accessories – Features like probe holders and euro bracing make for a cleaner and easier to work with design
• Ease of Installation – If there are videos or instructions available that makes things a whole lot better. A sump with bulkheads included is also extra nice
• Aesthetics – You want your sump to look cool right ? ?
• Low Noise – A bean animal design will have the lowest noise possible.

Conclusion

Sump purchasing will drive a lot of buyer anxiety to you. It’s the central operating hub of your reef tank. I hope I helped alleviate your anxiety in your purchasing decision. If you felt I left something out, please leave a comment below. Thanks for reading!
