Red Sea Magnesium – Foundation C (1L)

Strengthen your reef from the ground up with Red Sea’s Foundation C – Magnesium Supplement, scientifically formulated to support the growth of strong, healthy coral skeletons. As one of the four essential reef foundation elements, Calcium, Magnesium, Strontium, and Carbonate, magnesium plays a crucial role in maintaining the perfect chemical balance needed for coral health and vitality.

An imbalance of these elements can cause coral skeletons to form as fragile calcite, weakening the structural integrity of your reef. Foundation C ensures your system maintains the correct elemental ratio, promoting the formation of robust aragonite structures and a vibrant, stable ecosystem.
