Maintain vibrant coral coloration and health with Tropic Marin's Potassium supplement


Potassium is an essential main nutrient for all organisms. In seawater the natural potassium concentration is approximately 408 ppm. Potassium consumption is usually low since potassium does not form insoluble compounds and is only minimally adsorbed by other substances. Potassium levels can often be maintained by water changes alone, howver the use of zeolites and other adsorbers can result in a potassium deficiency. One indication of potassium deficiency is loss of color in corals and the retraction of polyps. With Tropic Marin Potassium the potassium concentration can be re-established to the natural level and may improve the health and colors of many corals.


Key Benefits

  • For supply of potassium in aquariums
  • Essential main nutrient for all organisms
  • Improve vitality and colors of many corals


Directions for Use

Tropic Marin Potassium contains 10 % potassium. A dose of 15 ml Tropic Marin Potassium will raise the potassium concentration in 40 gallons by approximately 10 ppm. Maximum recommended dose is 30 ml Potassium per 40 gallons of system water volume per day.


Caution: The natural potassium concentration (approx. 408 mg/l) should not be exceeded – higher potassium concentrations can be harmful for sensitive invertebrates. On the other hand, by adjusting the potassium concentration to the natural level with Tropic Marin Potassium may improve vitality and colors of many corals. Potassium concentration should always be measured before dosing.
