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 calcium Reef Advantage Calcium and carbonates (Reef Builder or Reef Carbonate).
Hint: If used with Reef Calcium, it is not necessary to exceed 380 mg/L total calcium.
Use Reef Status™: Calcium to measure calcium.
Do Not Overdose: Excess calcium may enhance the loss of carbonate alkalinity. Do not directly mix with any carbonate supplement. Best if calcium & carbonate additives are added on alternate days or at least 30 minutes apart.
