Elos Potassium Test Kit
Potassium is a very important chemical in biochemistry and cell biology. It is a major element in natural seawater with a similar concentration to Calcium, (levels of around 380-410 mg/lt). If in a standard aquarium, it rarely becomes a limiting element. In an aquarium where zeolite-based filtration (i.e. Filtra M) methods are used, its concentration often can become too low. In order to properly dose this element it is necessary to first test your potassium levels. To test properly we suggest the use of the Elos Aqua Test Potassium.
