Salifert Nitrite (NO2) Profi Test for saltwater aquariums, provides fast and accurate results when used to test your water parameters.Many nitrite test kits suffer from interference caused by amines e.g. naturally occurring and essential amino acids. This can result in a too low measured value, especially when the nitrite concentration is relatively low.Because of its unique formulation, the Salifert Test Kit does not suffer from amine interference, and offers full color development within one minute. Also, the color is very intense making the detection of even minute traces of nitrite easy.In a properly cycled aquarium, nitrite is converted to nitrate and then, if there are areas deprived of oxygen such as in live rock and other filter materials, this nitrate is converted back to nitrite and then transformed into harmless nitrogen gas.If this cycle breaks down then nitrites, which are extremely toxic to fish and invertebrates, can form in high concentration.Performs: 60 tests
