Red Sea Reef Foundation B (Alk) 5L

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.
