AquaHomeTest Refill-Kit K

The potassium test from Fauna Marin sets new standards in the determination of potassium content in marine aquariums: using a newly developed titration method, it provides extremely precise results in just a few easy steps.The determination of a correction value increases the accuracy of the results.-Measuring range: 300 - 500 mg/l-Resolution: 5 mg/lPotassium is a vital macronutrient for all living organisms. In natural seawater, the alkali metal is present in a concentration of 408 mg/l on average. In marine aquariums, the potassium concentration can usually be kept stable by regular water changes. Nevertheless, a deficiency of potassium can occur in individual tanks 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 retraction of 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 in case of too low values it is recommended to use Fauna Marin Elementals K to bring the potassium level back to the natural level and sometimes cause a vitality boost for various corals.If the potassium concentration in the water is too high, perform a partial water change. Solution C:Flammable liquid and vapor.Keep away from heat / sparks / open flame / hot surfaces.Do not smoke.Keep out of the reach of children.
