Seachem Aquarium accessories Reef Advantage Ca

Concentrated powdered ionic calcium supplement. Maintains magnesium and strontium. Can be added directly to the aquarium. Reef Advantage Calcium is a non-caustic mixture (pH 8.3-8.6) of ionic calcium designed to restore and maintain calcium at levels found in natural seawater. Calcium and carbonates are essential for all coral growth. If either becomes deficient, coral growth will stop, followed by a rapid decline in coral health. Reef Advantage Calcium also includes magnesium and strontium in proportions typical of usage rates (100:5:0.1 / Ca:Mg:Sr) and helps maintain these two important elements while keeping calcium levels. 250 g treats 8000 l.
