Reef Advantage Calcium 4kg

Reef Advantage Calcium is an enhanced non-caustic blend (pH 8.3-8.6) of ionic calcium designed to restore and maintain calcium to levels found in natural seawater. Calcium and carbonate are essential for coral growth. If either becomes deficient, coral growth will cease, followed by a rapid decline in coral health.

Reef Advantage Calcium also contains magnesium and strontium in amounts proportional to typical usage ratios (100:5:0.1, Ca:Mg:Sr). This allows one to maintain these two important elements while preserving calcium. Unlike lime water, Reef Advantage Calcium does not have a caustic pH and will not deplete magnesium. When used according to instructions, it will not deplete alkalinity.
