Nitrite is the chemical which ammonia is converted into by filtration bacteria. It is less toxic than ammonia but is still potentially lethal to livestock, if levels are allowed to rise then fish will become diseased and die. This test kit allows you to test for this waste product in the aquarium. It is vital to test for nitrite whilst the aquarium is new and also during the period whenever livestock is added. Periodical checks for nitrite in an established aquarium will check if filtration systems are working correctly.
