Red Sea Reef Foundation C Magnesium 5 Litre

The Red Sea Foundation C Magnesium 5 Litre is a high-quality supplement designed to maintain stable magnesium levels in reef aquariums. As part of the Red Sea Reef Care Program, Foundation C ensures the correct balance of magnesium alongside calcium and alkalinity, creating the conditions corals need to thrive.

Magnesium plays a crucial role in reef aquariums by stabilising calcium and carbonate concentrations. Without adequate magnesium, these elements can precipitate out of solution, leading to fluctuations that negatively affect coral health. By maintaining the proper magnesium level, Foundation C helps support coral skeleton formation, vibrant coloration, and long-term reef stability.

This ready-to-use liquid supplement is easy to dose and works seamlessly with Red Sea Foundation A (Calcium) and Foundation B (KH/Alkalinity). Together, these products deliver the balanced major elements required for strong coral growth and overall reef health.

The 5L container provides outstanding value for reef aquarists with medium to large aquariums, reducing the need for frequent replenishment and ensuring consistent water chemistry.
