Nitrite NO2 is a chemical nitrogen compound and contains nitrogen as an essential ingredient. The majority of nitrite in the aquarium is converted to nitrate (NO3) by nitrification. Nitrification is the bacterial oxidation of ammonium (NH4) / ammonia (NH3) to nitrite (NO2) and then to nitrate (NO3).
Particularly in newly established marine aquariums, nitrite concentrations that are significantly too high can arise if there are no sufficient bacterial cultures.
As a rule, "retracted" aquariums with functioning nitrification have no critical nitrite values. If the value nevertheless rises, it is essential to measure especially ammonia (NH3). Causes may be too high fish stock, too strong feeding but also used drugs that have disrupted or even destroyed the bacterial cultures.
The GIESEMANN nitrite test is a particularly precise test with a measurement range in the lower range up to 2.0 mg / l for regular checking of the water values.
