Calcium, magnesium, strontium and carbonate are the basic foundation elements of coral skeletons.
All of these elements need to be available in balanced proportions for positive coral health and growth.
Red Sea’s CALCIUM+ contains blended salts of calcium and strontium in the ratio required by corals and is part of Red Sea’s complete Reef Care Program.
