Nitrite NO2 is a chemical nitrogen compound containing nitrogen as an essential component. The majority of nitrite is converted into nitrate (NO3) by nitrification. Nitrification is the bacterial oxidation of ammonium (NH4) / ammonia (NH3) to nitrite (NO2) and then to nitrate (NO3).
Particularly in the case of newly established seawater aquariums, too high concentrations of nitrite can be produced, provided that sufficient bacterial cultures are not present.
As a rule, "retracted" aquariums do not have critical nitride values with nitrifica- tion. If the value nevertheless increases, it is absolutely necessary to measure ammonia (NH3). Causes can be too high fish stock, too much feeding, but also used drugs, which have disturbed or even destroyed the bacterial cultures.
The GIESEMANN Nitrite test is a particularly precise test with a measuring focal point in the lower range up to 2.0mg / l for the regular checking of the water values.
