Nitrite (NO2) is a chemical nitrogen compound and contains nitrogen as major constituent. The majority of nitrite in the aquarium reacts to nitrate (NO3) as a result of nitrification. Nitrification refers to the bacterial oxidation of ammonium (NH4) and ammonia (NH3) to nitrite (NO2) and subsequently to nitrate (NO3).

Nitrate (NO3) is a chemical nitrogen compound and contains as major constituent nitrogen, which is a key nutrient for corals. Nitrogen overconcentration however leads to over fertilisation and thus to increased algae growth.

Magnesium is a chemical element with the element symbol Mg.
Magnesium in conjunction with calcium is responsible for the alkalinity (KH), i.e. the hardness of water.

Phosphate (PO4) is a chemical compound and contains the element phosphor.

An overconcentration of phosphate in salt water aquariums leads to an over fertilisation of the corals that live in symbiosis with the zooxanthellae, which in turn leads to brown coloured corals.

Potassium is a chemical element with the element symbol K

A potassium shortage typically leads to a reduction or a complete stop of coral growth.

Iron is a chemical element, with the element symbol Fe.

Iron is a trace element that is indispensable to life for almost all species, in animals especially for the formation of blood.

Ammonium (NH4) and ammonia (NH3) are chemical compounds.

Ammonium (NH4) reacts to very toxic ammonia (NH3) in case of high pH values and elevated temperatures (typical for salt water 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 excrements.

The pH value represents the acidity (alkalinity) of water. The pH value is a measure for the acid or alkaline character of an aqueous solution.
