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).
• Increases alkalinity to help stabilize pH.
• Stronger than competing products.
• May be used as an inexpensive alternative to automated calcium reactor systems
• Free of phosphate, silicate, and organic material.
