Blend of high-purity powdered potassium, an important component of aragonite
(the mineral secreted as skeletal material by corals and other reef-building
marine organisms), complexed into pigments that enhance blue coloration of
some small-polyp stony corals, important to proper neurological function,
and depleted in marine aquaria by livestock.
May be used to combat potassium depletion that often accompanies the use
of zeolite-based filtration methods employed to maintain ultra-low-nutrient
Considerably stronger and more economical than liquid potassium solutions;
created for hobbyists maintaining multiple reef aquaria.
