This supplement is a combination of Reef Foundation A (Calcium & Strontium), Reef Foundation B (alkalinity Buffer) and Reef Foundation C (Magnesium). It includes calcium, magnesium, strontium and carbonate, which are the basic foundation elements of coral skeletons. All these elements need to be available in balanced proportions for coral health and growth. Reef Foundation ABC+ is a powdered blend of all of the foundation elements with the addition of potassium, bromine and iodine in unique ratio required by corals. Alternatively, instead of this single combined formula, you may want to have greater control by using the individual Reef Foundation A (Calcium & Strontium), Reef Foundation B (alkalinity Buffer) and Reef Foundation C (Magnesium) supplements
