Where available, add TurboStart® 700 or TurboStart® 900 for the most rapid and permanent ammonia/nitrite elimination possible.For best results, add FritzZyme® 7 Freshwater Nitrifying Bacteria or FritzZyme® 9 Saltwater Nitrifying Bacteria to naturally reduce toxic ammonia and nitrite quickly.Treat replacement water with FritzGuard® Water Conditioner with aloe vera and vitamin E to greatly reduce fish stress and the chance of infection.Remove as much waste from the bottom of the aquarium as possible.The chronic toxicity is where the fish will have diseases and a general failure to thrive. This is the Toxic level in the chart below. The acute toxicity is where the fish die in hours or days. Nitrite is not a poisonous as many would have us believe. If the nitrite level is above 0.5 ppm, perform a small water change. In the brackish aquarium, pH should be maintained between 7.8 and 8.4, with alkalinity between 10 and 20 dKH (180 ppm to 360 ppm). Nitrites are products of the decomposition of food proteins.Always reduce feeding temporarily if any nitrite or ammonia is detected.

If nitrite is present, take immediate steps to reduce it. Nitrite levels should be at 0 ppm (parts per million). Use a Fritz Nitrite Test Kit to determine if there is nitrite in your aquarium. If a fish is ill or dies, it’s wise to test for nitrite to ensure that is not contributing to the problem. Any elevation of nitrite levels is a red flag that indicates a problem brewing in the tank. When you do your monthly testing, include nitrite testing as part of the routine. However, even after an aquarium is initially “cycled,” it is not unusual for your tank to experience nitrite “spikes” from time to time. Regular testing for nitrite is important because even low levels of nitrite affect the red blood cells of fish, reducing their ability to carry oxygen, thus causing suffocation and fish death.ĭuring the startup of a new tank, nitrite levels will soar and can stress or even kill fish. As the biological filter develops and grows, the bacteria use nitrite as a food source, converting it to non-toxic nitrate, thus reducing the level of nitrite in the aquarium. It is produced as nitrifying bacteria in the biological filter break down ammonia. Nitrite is a toxic waste material found in varying concentrations in most aquariums. Nitrites are one of the most harmful pollutants in aquarium water.
