Ammonium (NH4) and ammonia (NH3) are are both forms of Nitrogen. Ammonium (NH4) reacts to high pH values and elevated temperatures turning into very toxic ammonia (NH3), typically in saltwater aquariums. Ammonia is a chemical compound consisting of nitrogen and hydrogen and is created during the natural decomposition of dead plants and animals as well as animal waste.
An over-concentration of ammonia can be reduced through an efficient nitrification (e.g. promoted by starter bacteria) and through a regular water exchange. Suddenly occurring elevated ammonia concentrations (e.g. resulting from dead animals) should immediately be removed by a generous water exchange.
Ammonia is very hazardous to the health of all aquarium species and should therefore be measured regularly, to keep the total value of ammonium in the aquarium below 0.2 mg/l. The Giesemann NH3 test was specifically developed for saltwater aquariums to analyze the total ammonium, which is the sum of ammonium (NH4) and ammonia (NH3).
