Potassium Solution Primarly for Reef Aquaria Housing SPS Corals Overview Highly-concentrated ionic potassium solution. Provides potassium, an important component of aragonite (the mineral secreted asskeletal material by corals and other reef-building marine organisms), complexedinto pigments that enhance blue coloration of some small-polyp stony corals, importantto proper neurological function, and depleted in marine aquaria by livestock. 80,000 ppm K; considerably stronger and more economical than competingpotassium products. May be used to combat potassium depletion that often accompanies the use ofzeolite-based filtration methods employed to maintain ultra-low-nutrient aquaria. Formulated by a marine scientist.
