Designed to restore & maintain calcium to levels found in natural seawater that supports healthy coral growth.
Calcium & 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 is a non-caustic (ph 8.3-8.6) optimized blend of ionic calcium. It also includes magnesium & 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. Unlike limewater (Kalkwasser), it does not have a caustic pH and will not deplete magnesium. Used as directed, it will not deplete alkalinity.
To prevent coral problems, you must provide Reef Advantage Calcium™ and carbonates in Reef Builder (below) or Reef Carbonate (below).
