Seachem

Seachem Reef Advantage Calcium ™ is equivalent to dry Reef Complete™. It 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 amounts proportionate to typical utilization ratios (100:5:0.1, Ca:Mg:Sr). This allows one to maintain these two important elements while maintaining calcium. If either usage or precipitative loss results in a more rapid loss of either magnesium or strontium, then Reef Advantage Magnesium™, Reef Advantage Strontium™, or Reef Strontium™ may be employed. Unlike limewater (kalkwasser), Reef Advantage Calcium™ does not have a caustic pH and will not deplete magnesium. Used as directed, it will not deplete alkalinity. 250 g treats 8,000 L (2,000 gallons).

I have tried multiple methods with regard to calcium and alkalinity management in the reef aquarium and find myself coming back to Seachem.

“Great!”
5.0

I like the Seachem products, and have had great success using them. They are an excellent value. Great quality for the price! The calcium dissolves easy and does not cloud the water at all. I like using it as opposed to kalk because it does not effect the PH and Alkalinity as much.
