Nitrite ions (NO2–) and nitrate ions (NO3–) are formed from ammonium (NH4+) in the nitrification process. In the first stage of the bacterial process, nitrite is formed, which is highly toxic to freshwater animals. When nitrification is working, the nitrite is converted into nitrate in the second stage. In saltwater aquariums, increased nitrate concentrations disrupt the growth of sensitive corals. A danger of high nitrate levels for all aquariums is that they strongly encourage algae growth. In rare cases, nitrate deficiency situations can also occur. Therefore, the nitrite and nitrate concentrations of the aquarium water should be checked regularly.

Nitrite should generally be below 0,2 mg/l in all aquariums. Levels below 50 mg/l are recommended for nitrate in freshwater aquariums, while concentrations in seawater should not exceed 20 mg/l. When caring for hard corals, aim for nitrate levels below 10 mg/l. Lower limits for nitrate depend on the general conditions in the aquarium.
