UNS Aquarium Features

Ultum Nature Systems (AKA UNS) are considered the premium rimless aquarium brand in our industry. They are heavily favored when it comes to planted tanks. The main selling point is their extremely precise design.

Ultum Nature Systems Glass Construction

UNS Aquarium Glass

The glass on the Ultum Nature Systems have 45 degree mitered edges. They use high-grade german silicone to not only secure the tank but to have a quality view without obstruction. All aquariums come with a black leveling mat. They are made of low iron 91 clarity Diamant glass.

The use of 91 clarity Diamant glass is another level of quality when it comes to aquariums. It is not your ordinary low iron glass.

Diamant is typically used in commercial office windows, interior design, furniture, and display cabinets. This type of glass isn’t used in aquariums because of its price. UNS doesn’t skip anything on quality and materials to get the highest clarity glass you can find on the market. They are well known with their UNS Systems brand logo laser etched on the right bottom side of every tank they construct.

Ultum Nature Systems Cabinets

One of the biggest benefits of purchasing a UNS aquarium is have access to their cabinets. The UNS cabinets are one of the most modern and clean looking stands you will find today. They are made of natural wood materials and come fully assembled out of the box. They are far superior to any stand you can buy standard from a pet store.

They are designed to house Canister filters and there is a 45 degree mitered cut at the top of the cabinet door to allow for a grip when opening the doors. All the cabinets fit with UNS aquariums.

Ultum Nature Systems Craftsmanship

UNS Aquarium Tank and Cabinet

Ultum Nature Systems craftsmanship is the pinnacle of the planted tank community. Their glass construction and materials are top notch and unique in the industry. Few if any manufacturers use a commercial grade Diamant glass to save on materials costs. Each glass tank is laser etched with their trademark UNS brand and the aquariums are designed for clean lines and maximum clarity.

On the cabinet side, the cabinets are some of the most modern looking and elegant aquarium stands you will find in the industry. They have leveling knobs and are designed to last and look amazing. Everything fits seamlessly and the tanks look like a work on art on top of the cabinet. The black leveling mat is nonexistent when installed correctly.

Together both the aquariums and cabinets make a high-end design that will make you the envy of all your aquarium friends and be a conversation piece in the living room or office.

UNS Aquariums Value for the Money

Ultum Nature Systems Aquariums come in a variety of sizes designed with the aquascaper in mind. All models have a cabinet available that fits with the tank and made with their low iron diamant glass. I feel the value for the money is great given the quality of these aquariums and the cabinets available for them. UNS has the following model lines for their aquariums:

  • Rimless Cube Glass Aquariums
  • Standard Ultra Clear Rimless Glass Aquariums
  • Shallow Rimless Aquariums
  • All-In-One Aquarium Tanks

UNS Cube Glass Aquariums

UNS Cube Aquariums are nano square shaped tanks. They can be great for tighter spaces. The small aquariums are perfect for shrimp tanks, betta fish tanks, and stunning mini aquascapes.

UNS Aquariums Ease Of Use

The aquarium itself is super simple. It’s a clean rimless aquarium that comes with a leveling mat. It’s the cabinets that are the big selling point when you purchase these aquariums. The cabinets come already assembled. This is a big difference between other brands like Red Sea or WaterBox who will have the cabinet come in a kit where you would need to assemble it yourself. This saves you time and risk of error.

Ultum Nature Systems Product Support

This is a major knock on Ultum Nature Systems. They do not have much in the way of product support. They really rely on their retailers to provide guidance and support for claims. The claims will then run through the retailer. This is why you must purchase these aquariums from an authorized dealer. Most dealers are local fish stores, but a premier online seller of UNS aquariums exists online. That would be BucePlant, who is the go to for advanced freshwater equipment and plants. I would recommend if you are going to purchase a UNS Aquarium aquarium online that you purchase it from BucePlant.

UNS Aquariums Price

UNS due to their unique to the industry leading glass, construction process, and brand name are one of the more expensive pure rimless tanks on the market. There certainty are cheaper brands out there if they are out of your budget range, but the UNS’s premier construction, glass, and brand name really stand out.

Among cabinets, they are one of the finest cabinets you can purchase outside of getting one custom made. The price for them is worth it. Together as a package, they are an excellent value for a high end aquarium.

UNS Aquarium Review Closing Thoughts

Ultum Nature Systems aquariums offer a great package for those aquascapers lookers for a high end looking setup. The rimless aquarium is one of the highest quality out there with a unique commercial grade glass type. The cabinets are great looking and designed for planted tanks. If you are looking for a show stopping setup to compliment your home or office, UNS Aquariums are the way to go!

Marine Velvet - Surviving and Preventing A Tank Terror
Have you come to this post wondering if your fish has Marine Velvet? I feel your pain if you have. In my over 25 years of experience, Marine Velvet is the most common disease tank crasher in the hobby. It strikes fast, kills fast, and most people aren't prepared for it. It's the one disease I fear the most in my saltwater aquarium. In fact, it is labeled one of the deadly three in my how to quarantine saltwater fish post.
