Resolution: 5 mg/l
Potassium is an essential macronutrient for all living things. In natural seawater, the alkali metal is present in an average concentration of 408 mg/l. In a seawater aquarium, the potassium concentration can usually be kept stable by regularly changing the water. Nevertheless, a lack of potassium can occur in individual pools due to the use of zeolites and other adsorbers. An indication of a possible potassium deficiency is the clear discoloration of the corals and the retraction of the polyps. In the reef aquarium, the potassium concentration should be checked regularly and kept at a value between 380 and 420 mg/l.

To increase the potassium concentration when the values ​​are too low, we recommend using Fauna Marin Elementals K in order to adjust the potassium content back to the natural level and sometimes to bring about a vitality boost for various corals.

If the potassium concentration in the water is too high, a partial water change is carried out.
