API Nitra Zorb 210G KR86

Nitra-Zorb is a water filtration medium comprised of natural and synthetic ion-exchange resins in a flow-through pouch. Nitra-Zorb selectively removes ammonia, nitrite and nitrate from freshwater aquariums.

This product helps establish new aquariums by controlling the levels of ammonia and nitrite and preventing fish loss. Nitra-Zorb is also very useful in established aquariums whenever ammonia and nitrite is detected. Many advanced hobbyists are concerned about nitrate in the aquarium. Nitra-Zorb will help keep nitrate under control. Nitra-Zorb is easily recharged in a solution of warm table salt. Nitra-Zorb can be used in any filter.

When setting up a new aquarium use Nitra-Zorb continuously as directed. Whenever ammonia or nitrite is indicated by testing, Nitra-Zorb is exhausted and must be recharged. Follow the recharging instructions and continue to use Nitra-Zorb while the biological filter becomes established.

Nitra-Zorb is ideal for delicate species of fish and plants that thrive in soft water aquariums. This product will not alter pH, hardness, or alkalinity levels, and will not remove trace elements such as iron. Use Nitra-Zorb to maintain high water quality and fish vigor in any freshwater aquarium.

The level of ammonia, nitrite and nitrate removed depends on the size of the Nitra-Zorb pouch, size of the aquarium, flow rate of the aquarium filter, and how much ammonia, nitrite and nitrate is being produced in the aquarium daily. A 3.7 oz (105 g) pouch of Nitra-Zorb in a 20 U.S. gallon (75.6 L) aquarium will remove 5.0 ppm ammonia, 1.0 ppm nitrite, and 20 ppm nitrate in 24-48 hours. If the aquarium is overstocked or fed heavily, the build-up of ammonia, nitrite and nitrate may occur as fast it can be removed by Nitra-Zorb. Nitrate levels may be so high that they are well above the maximum level on nitrate test kits. It may be necessary to continually recharge and reuse the Nitra-Zorb pouch until the nitrate level drops within the test kit range.
