The potassium test from Fauna Marin sets new standards in determining the potassium content in saltwater aquariums: by titration, it delivers extremely precise results in just a few simple steps using a newly developed method.
The determination of a correction value increases the accuracy of the results.
Measuring range: 300 - 500 mg / l
Resolution: 5 mg / l
Potassium is a vital macronutrient for all living things. In natural seawater, the alkali metal is present in an average concentration of 408 mg / l. In a saltwater aquarium, the potassium concentration can usually be kept stable by regular water changes. Nevertheless, a deficiency of potassium can occur in individual pools due to the use of zeolites and other adsorbers. A sign of a possible potassium deficiency is the clear discoloration of the corals and the ingestion 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, the use of Fauna Marin Elementals K is recommended, in order to adjust the potassium content to the natural level and to bring about a vitality boost for various corals.
