Designed to maintain natural seawater calcium levels without altering pH, it supports optimal coral growth by delivering calcium alongside magnesium and strontium in natural ratios. Its 100% soluble, ammonia-free formula ensures easy dosing and superior reef vitality, making it the go-to choice for serious reef enthusiasts. ## Description Reef Complete® is a concentrated (160,000 mg/L) optimized blend of ionic calcium designed to restore and maintain calcium to levels found in natural seawater without affecting pH. 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. To prevent this you must provide calcium (Reef Complete®) and carbonates (Reef Builder™ or Reef Carbonate™). Reef Complete® 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. Reef Complete® is a blended product. It is not simply calcium chloride. Commercially available calcium chloride contains ammonia. Unlike other ionic calcium supplements, Reef Complete® is blended to a higher pH in order to force the ammonia to gas off into the atmosphere. In addition, Reef Complete® is more concentrated than any other liquid product on the market. Reef Complete® contains 160,000 ppm calcium. Our nearest competitor’s product is only 110,000 ppm calcium. Review: Part of a nutritional breakfast for reef tanks. - 100 gallon reef tank. I go through a lot of seachem reef products.
