  • High-purity powdered calcium.
  • Increases the concentration of calcium in marine aquarium water to provide corals and
    other reef-building invertebrates with one of the most important elements required for growth.
  • Stronger and more economical than liquid calcium solutions; created for hobbyists
    maintaining multiple reef aquaria.
  • Formulated by a marine scientist.
