  • Calcite

    Calcite is a naturally occurring calcium carbonate media One of the advantages of Calcite is its self limiting property When properly applied it corrects pH only enough to reach a non corrosive equilibrium It does not overcorrect under normal conditions Upon contact with Calcite acidic waters slowly dissolve the calcium carbonate to raise the pH which reduces the potential leaching of
