It’s all in the balance

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.
