Seachem Aquarium accessories Reef Adv. Calcium

Concentrated ionic calcium supplement in powder form. Maintains magnesium and strontium. Can be added directly to the aquarium. Reef Advantage Calcium is a non-caustic blend (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 any 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 allows for the maintenance of these two important elements while keeping calcium levels stable. 500 g treats 16,000 l.
