Red Sea Reef Foundation™ C – Magnesium Red Sea Reef Foundation C is a concentrated magnesium supplement designed to maintain natural seawater magnesium levels in reef aquariums. Magnesium is a vital element that helps stabilize calcium and alkalinity, preventing unwanted precipitation and ensuring these essential elements remain available for coral growth. Proper magnesium levels support healthy skeletal development in stony corals, coralline algae growth, and overall reef stability. The liquid formula is suitable for both manual and automated dosing and is intended to be used as part of Red Sea’s Reef Foundation supplementation program.
