Potassium is a chemical element with the element symbol K
The name potassium originates from its discovery within potash. Potassium is one of the most prevalent elements and appears in numerous minerals worldwide.
Potassium should always be contained in sufficient concentrations in sea water aquariums.
A potassium shortage typically leads to a reduction or a complete stop of coral growth.
A potassium shortage in stone corals expresses itself in a fading of the coral colours. Over or under concentrations of potassium in salt water can be corrected by a partial water exchange.
The optimal potassium concentration in a salt water aquarium ranges between 360 and 410 mg/litre.
