High Purity Calcium Media for Placement in Reef Aquarium Media Reactors


  • High-purity natural mineral that may be employed in traditional calcium reactors, or even
    blended in to pre-existing aquarium substratum, to gradually increase and maintain the
    calcium concentration and alkalinity in marine aquaria.
  • Strong source of calcium, the most abundant cation by percent mass in aragonite, the
    mineral secreted by reef-building organisms to form skeletal material.
  • Through dissolution, provides calcium, magnesium, strontium, potassium, and carbonates.
  • Aids in increasing alkalinity to stabilize pH and encourage rapid biogenic aragonite
  • Optimal average particle size for use in media reactors and calcium reactors.
  • Free of chloride and sulfate.
