Salifert Nitrite Profi-Test: 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. This test kit does not suffer from amine interference and offers full color development within one minute, making the detection of even minute traces of nitrite easy.
