Chemical filter media for freshwater aquariumsRemoves ammonia, nitrite, and nitrate from aquarium waterRechargeable chemical filter media for extended aquarium useA blend of natural and synthetic ion exchange resins that selectively remove ammonia, nitrite, and nitrate. In new aquariums, Nitra-Zorb controls the level of toxic ammonia and nitrite during initial development of the biological filter. In established aquariums, it helps control sudden surges in ammonia and nitrite caused by the addition of new fish, or anytime ammonia or nitrite is detected. 128 grams. For use in freshwater aquariums. Use one 128 gram pouch of Nitra-Zorb per 55 gallons of water.Please click on "More Information" for directions for use.

Chemical filter media for the reduction of ammonia, nitrite and nitrate Rechargeable chemical filter resin for use with new or established freshwater aquariumsUse Nitra-Zorb to help reduce fish loss when setting up and cycling new aquariums A water filtration medium composed of natural and synthetic ion-exchange resins. Selectively removes toxic ammonia, nitrite, and nitrate. Contains no phosphate, will not affect pH, and is compatible with activated carbon. Media, in convenient pouch, can be easily recharged with freshwater aquarium salt. Small 20 gallon size fits easily in Whisper filters. For freshwater use only.

The Nitrate Reductor is designed specifically for safe nitrate removal. Filled with Bactoballs for a huge amount of surface area, nitrate-reducing bacteria are easily maintained and fed using the enclosed Denimar tablets for precise dosing. The unit also features probe mounts for use with an ORP controller so that the bacteria can be fed in exact relation to NO3 levels. Deniballs can also provide automatic feeding for independence from chemical feeding methods (none included). Place inside the tank, beside it, or in a sump. Comes complete with re-circulating pump. 6.4" L x 6.4" W x 20.8" H.Nitrate Reductor for fresh and saltwater tanks up to 250 gallons.Deniballs Refill - Patented, organic plastic media for automatic feeding. 0.8 L. 24 balls.Denimar Refill - Chemical food supplement for Mini and Regular NO3 Reductors. 150 grams powder.

Removes nitrates in marine systemsEngineered for good water flow characteristics, and maximum adsorptionNitrate Sponge is a granular zeolitic medium which works by two methods: 1) It slowly, but directly adsorbs small amounts of ammonia that are released by fish and natural processes, and 2) it fosters anaerobic bacterial denitrification due to its physical porous structure. This denitrification slowly reduces nitrate levels in the aquarium. It works well in freshwater tanks or tap water to remove toxic ammonia directly Nitrate Sponge prolongs the time allowed between water changes by keeping nitrates low. 2 qt. jar treats a 50 gallon tank. This media (like all media) must be used in a media bag.
