Potassium supplement for aquaria
Potassium is an essential main nutrient for all organisms. In seawater, the natural potassium concentration is ca. 408 ppm. Potassium consumption in saltwater aquaria usually is small since potassium does not form insoluble compounds and is only minimally absorbed by other substances. The potassium level can often be maintained by water changes. The use of zeolites and other adsorbers can result in a potassium deficiency. One indication of potassium deficiency is the loss of colour in corals and the retraction of polyps.
With Tropic Marin® POTASSIUM the potassium concentration can be re-adapted to the natural level and may improve the vitality and colours of many corals.
PRO-CORAL POTASSIUM contains 10 % potassium. A dosage of ½ fl. oz./15 ml Tropic Marin® POTASSIUM will raise the potassium concentration of 40 US-gal./150 l by approximately 10 ppm. The maximum recommended dose is 1 fl. oz./30 ml POTASSIUM per 40 US-gal./150 l water per day.
The natural potassium concentration (approx. 408 mg/l) should not be exceeded – higher potassium concentrations can be harmful to sensitive invertebrates. On the other hand, adjusting the potassium concentration to the natural level with Tropic Marin®POTASSIUM may improve the vitality and colours of many corals. Potassium concentration should always be measured before dosing Tropic Marin® POTASSIUM.
