Complete source of the elements and molecules that are directly used by corals, clams, and other reef-building invertebrates and organisms to create skeletal material and grow; provides calcium (140,000 ppm), strontium, magnesium, and potassium in approximately the same ratios in which they occur in aragonite. Very strong source of carbonates (derived from aragonite), the other important group of ions involved in aragonite formation. Increases alkalinity to help stabilize pH. Free of phosphate, silicate, and organic material. Stronger than competing products. Formulated by a marine scientist. |
