Aquarium Pharmaceuticals Fresh Water Nitrite Test Kit reads total nitrite (NO2) levels in parts per million (ppm) from 0 ppm to 5 ppm. Regular testing for nitrite is an essential part of routine aquarium maintenance.
Aquarium water should be tested for nitrite every other day when the aquarium is first set up. In established aquariums, test for nitrite weekly to make sure the nitrite level does not rise.
