In order to maintain good water quality, a range of test kits that offer accuracy, consistency and support, is an integral part of a successful aquarium. ELOS AquaTest Kits are...
Red Sea’s Seawater Refractometer offers exceptional accuracy, for measuring the absolute salinity of seawater at a temperature of 25oC/77 0F. Most refractometers used within the aquarium hobby are not specifically...
A reef aquarium will need the following tested in addition to the above:
We have provided an explanation for each parameter, what the ideal ranges are, and how often to test below for your reference. We carry the most trusted saltwater test kits on the market. Please drop us a e-mail or chat us if you have any additional questions:
|Parameter||What Is It?||Fish Only Range||Reef Tank Range||How Often to Test|
|Specific Gravity||Measurement of density of a liquid - in this case salt. Too high or low gravity can be harmful and deadly to fish and corals||1.019 - 1.026||1.023 - 1.026||Constantly. In Reef tanks this can be monitored throughout the day by an aquarium controller.|
|pH||Acidity or basicity in your water. Swings in pH are harmful and even deadly to both fish and corals||8.1 - 8.3||Constantly. In Reef tanks this can be monitored throughout the day by an aquarium controller.|
|Ammonia & Nitrite||Highly toxic products of the aquarium's nitrogen cycle. Produced by fish, food waste, and decaying matter. Harmful and deadly to both fish and corals. A direct result of a tank that is undergoing cycling or an overstocked tank.||0 ppm||0 ppm||When cycling a tank, weekly. After cycling test weekly when new additions are added and monthly when under maintenance|
|Nitrate||Final product of the nitrogen cycle. Produced by bacteria. High levels will stress out fish and coral and fuel excessive algae growth. Nitrates are often the reason for water changes as water changes reduce these levels.||Less than 25 ppm||Less than 5 ppm||Test weekly or monthly|
|Alkalinity||The measure of bicarbonate. It should be maintained at 9-12 DKH. Alkalinity keeps pH and calcium levels stable, which will allow for corals to grow and build their skeleton structure.||9-12 DKH||9-12 DKH||Weekly|
|Calcium||Used by corals to grow and build a skeleton||N/A||380-450 ppm||Test daily when determining dosing schedule, then test weekly after that.|
|Magnesium||Helps maintain stable calcium and alkalinity. Also reduces precipitation.||N/A||1200-1400 ppm||Weekly|
|Phosphate||Fuels Algae growth and inhibits coral growth. Can be kept under control by RODI water, Filter material like GFO, or equipment like algae turf scrubbers. Helpful to test in fish only system to keep algae at bay, but RODI water is generally sufficient.||N/A||Less than 0.05 ppm||Weekly|
