About potassium

Potassium is a vitally important macro-nutrient for all living beings. In natural ocean water, this alkali metal is present in an average concentration of 408 mg/l. In a saltwater aquarium, the potassium concentration is usually kept stable by regularly changing the water. Nevertheless, a lack of potassium can occur in individual aquariums tanks due to the use of zeolites and other adsorbents. One sign of a possible lack of potassium is clear discolouration of corals and retraction of polyps. The potassium level in a saltwater aquarium should be checked regularly to ensure that the level is between 380 and 420 mg/l.
