Tropic Marin Pro-Reef is a pharmaceutical-grade sea salt made from pure salts containing all 70 trace elements of natural seawater. It is formulated with optimized concentrations of calcium and magnesium to promote coral growth and adjusted buffering that stabilizes pH and alkalinity, even alongside calcium reactors and other supplementation. The mix dissolves fast and clear and is free of nitrate and phosphate.
