Seachem Reef Advantage Calcium – 500 g

Seachem Reef Advantage Calcium is a non-caustic (pH 8.3 – 8.6) optimized blend of ionic calcium designed to restore and maintain calcium to levels found in natural seawater. Calcium and carbonates are essential to all coral growth. If either becomes deficient, coral growth will cease, followed by a rapid decline in coral health. Reef Advantage Calcium also includes magnesium and strontium in amount proportionate to typical utilization ratios (100:5:0.1, Ca:Mg:Sr). This allows one to maintain these two important elements while maintaining calcium. Will not deplete magnesium, and when used as directed, will not deplete alkalinity.
