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.

Reef Foundation B is a complex of carbonate and other buffers present in seawater that maintain a proper alkalinity and pH and is part of Red Seas complete reef care program. Regular use of Reef Foundation B will ensure a balanced formation of coral skeleton. 

For best results, dose according to a measured drop of alkalinity and in conjunction with Reef Foundation A & C.

Liquid: 1ml will raise the Alkalinity level of 100L by 0.036 meq per litre (0.1dKH) .
