Reef•Sculpture parts A & B, when used together and as directed are an ionically balanced calcium and alkalinity control system. Unlike many other products which will cause a buildup of chlorides or other ions, Reef•Sculpture will maintain seawater ratios of important ions. When used as directed it will maintain calcium and buffering capacity in the same ratio found in natural seawater. It contains no acetate, gluconates, polygluconates or other unnecessary organics to pollute your aquarium. It is phosphate and nitrate free. Use in aquarium keeping. Proper control of calcium level is imperative for the health and growth of corals and many other invertebrates. If the calcium concentration is too low, growth rates will suffer. If it is too high, alkalinity or buffering capacity will be diminished, leading to possible instability of pH. Sufficient magnesium levels are also necessary to maintain the proper balance. It is therefore recommended that the hobbyist measure and control the levels of calcium, magnesium
