Seachem Complete 250ml

Reef Complete is a concentrated (160,000 mg/L) optimized calcium ion blend designed to restore and maintain calcium at levels found in natural seawater without affecting pH.Calcium and carbonate are essential for the growth of all corals; if either becomes deficient, coral growth will cease, followed by a rapid decline in coral health; to prevent this, you must provide calcium (Reef Complete) and carbonate (Reef Builder or Reef Carbonate).
