Nitrate ions (NO3–) are formed as the end product of nitrification from ammonium (NH4+). In the first stage of the bacterial process, nitrite (NO2–) is formed, which is highly toxic, especially to freshwater animals. If nitrification is working, the nitrite is converted into the comparatively non-toxic nitrate in the second stage. Elevated nitrite values above 0,05 mg/l occur primarily in pools in the run-in phase or in pools with nitrate filters.

Nitrates affect the water quality in the aquarium: 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 some reef aquariums, extremely nutrient-poor conditions are created - this can lead to nitrate deficiency situations. Therefore, the nitrate concentration of the aquarium water should be checked regularly.

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.
