Tropic Marin Potassium 500ml

Regular price £14.98

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 adsorbed 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 loss of color 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 vitality and colors of many corals.

Benefits:

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

How to use:

PRO-CORAL POTASSIUM contains 10 % potassium. 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. Maximum recommended dose is 1 fl. oz./30 ml POTASSIUM per 40 US-gal./150 l water per day.
