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 coral health and growth.
Red Sea’s KH/ALKALINITY is a complex of carbonate and other buffers present in seawater that maintain proper alkalinity and pH, and is part of Red Sea’s complete Reef Care program.
