The potassium test from Fauna Marin sets new standards in determining the potassium content in saltwater aquariums: using titration, it delivers extremely precise results in just a few, easy-to-implement steps using a newly developed method.
Determining 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 saltwater aquariums, the potassium concentration can usually be kept stable by changing the water regularly. However, a potassium deficiency can occur in individual tanks due to the use of zeolites and other adsorbers. A sign of a possible potassium deficiency is the significant 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 if values are too low, we recommend using Fauna Marin Elementals K to adjust the potassium content back to the natural level and sometimes 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.
