Nitrite (NO2) is a chemical nitrogen compound and contains nitrogen as major constituent. The majority of nitrite in the aquarium reacts to nitrate (NO3) as a result of nitrification. Nitrification refers to the bacterial oxidation of ammonium (NH4) and ammonia (NH3) to nitrite (NO2) and subsequently to nitrate (NO3).
