Product Description
Red Sea Reef Foundation C (Mg) - 500ml
The Red Sea Reef Foundation C (Mg) - 500ml is a magnesium supplement for reef aquariums, designed to replenish magnesium used in balanced coral skeleton formation and stable seawater chemistry.
Magnesium Support for Balanced Reef Chemistry
Foundation C provides magnesium salts for reef systems where magnesium is depleted through coral growth, coralline algae growth and water chemistry interactions. Maintaining magnesium helps support balanced calcium and alkalinity behaviour and reduces the risk of foundation elements becoming chemically unstable.

- Magnesium supplement for reef aquarium foundation maintenance.
- Supports balanced formation of coral skeleton.
- Helps maintain seawater ionic strength and overall reef stability.
- Ready-to-dose liquid format for manual dosing or dosing pump use.
- 500 ml bottle is practical for smaller systems or moderate magnesium correction routines.
- Part of Red Sea's Foundation A, B and C supplement system.

Application Notes
Use Red Sea Reef Foundation C when magnesium testing shows levels are below the aquarium's target range. Magnesium should be maintained with calcium and alkalinity because unbalanced levels can affect coral growth and overall reef chemistry stability.
