Reef Building Supplement for Coralline Algae, Corals, Clams, & Other Marine Invertebrates


  • Complete source of the elements and molecules directly used by corals, clams, and other
    reef-building invertebrates and organisms to create skeletal material and grow.
  • Provides calcium, strontium, magnesium, and potassium in approximately the same ratios
    in which they occur in aragonite, the mineral that is primarily secreted by reef-building marine
    organisms under normal environmental conditions.
  • Very strong source of carbonates, also involved in aragonite formation; twice the calcium
    relative to carbonates compared to natural aragonite.
  • Formulated by a marine scientist.
