Keep your marine and freshwater aquariums clean and healthy with Kent Marine Nitrogen Sponge Ammonia & Nitrate Absorber Filter Media. Fish waste, uneaten food and other organic matter can cause toxic levels of ammonia and nitrate which can cause stress, illness and even death. Kent Marine Nitrogen Sponge Ammonia & Nitrate Absorber Filter Media is a granular zeolitic medium that directly adsorbs ammonia in freshwater and fosters anaerobic bacteria growth to reduce nitrate levels in both marine and freshwater aquariums. Place in a large mesh bag or in a canister filter directly in the water flow.
Adsorbs and removes toxic ammonia and nitrates that can build up from fish waste, uneaten food, and other organic matter in your aquarium
Fosters growth of beneficial bacteria to promote aquarium health
Effective and safe for both marine and freshwater aquariums
Can be used in de-nitrators or other slow-flow applications
Easy to use: just administer 1 cup for every 20 gallons of water
Use 1 cup for each 20 gallons of aquarium water. More can be used for greater effectiveness. Rinse with fresh water before use (preferably with reverse osmosis or de-ionized water). Place in a large mesh bag (800 micron) or a canister filter directly in the water flow. Make sure water flows through the material and not around it. To control ammonia in freshwater systems, granules can be replaced weekly. When used for controlling nitrates, replace only half of the granules every 3 to 6 months. 3.3 lbs (1 qt.) treats 50 gallons and will reduce nitrates by about 20 ppm. Several weeks will be required to see an appreciable drop in nitrates. Test nitrates and ammonia regularly. Can be used as an excellent media in de-nitrators and other slow- flow applications.
