Red Sea Reef Foundation C (Mg)

Magnesium Supplement for Balanced Coral Skeleton Growth

For reef systems to thrive, corals must be able to deposit strong, stable skeletons — and that can only happen when key foundation elements are available in the correct ratios. Magnesium plays a crucial role in maintaining the balance between Calcium, Carbonate, and Strontium, preventing the formation of brittle calcite and instead supporting robust aragonite skeletons.

Reef Foundation C delivers a highly pure, blended magnesium supplement formulated to match the exact biological demands of growing corals. As part of Red Sea’s Reef Care Program, it integrates seamlessly into a complete, science-based foundation-element routine, giving reef-keepers precision control over their water chemistry.
