Reef Complete, by Seachem, is a concentrated blend of ionic calcium intended to restore or maintain calcium levels at natural seawater levels. Rather than just calcium chloride, is specifically blended to a higher pH, which forces the ammonia found in commercially available calcium chloride to “gas off into the atmosphere”. Reef Complete by Seachem also contains strontium and magnesium, which helps the hobbyist maintain these two elements at appropriate levels.

Additionally, Seachem claims that Reef Complete is more concentrated than other available liquid products on the market, containing 160,000 ppm calcium. Seachem notes that their “nearest competitor’s product is only 110,000 ppm calcium.”

Reef Complete is available in 100ml, 250ml, 500ml, 2L, 4L and 20L.

As with any supplement, Reef Tools strongly recommends to TEST BEFORE YOU DOSE!
