In this test, the total concentration of ammonium / ammonia is measured. In freshwater applications, a total concentration of ammonium / ammonia of 0.1 mg/l (ppm) is normal under standard conditions, although an upper limit of 0.5 mg/l (ppm) should not be exceeded. Ammonium is the product of nitrogen mineralization in which bonded nitrogen from food remains and excrement is converted to NH4+ by bacteria. Depending on the pH value, there is an equilibrium between ammonium ions NH4+ and ammonia NH3 in the water.
