Red Sea Reef Care Magnesium Foundation C is a premium magnesium supplement formulated to maintain and replenish magnesium levels in reef aquariums. Magnesium plays a critical role in coral health, particularly in supporting skeletal growth for hard corals and maintaining the delicate balance between calcium and alkalinity. By ensuring stable magnesium levels, this supplement promotes strong coral growth, healthy reef ecosystems, and overall aquarium stability.
Optimized Magnesium Formula – Provides a pure, easily absorbed form of magnesium for corals, fish, and invertebrates.
Balances Reef Chemistry – Helps stabilize calcium and alkalinity levels, preventing imbalances that affect coral health.
Boosts Coral Growth – Essential for coral calcification, ensuring SPS and LPS corals thrive.
Highly Concentrated – Long-lasting formula requiring minimal dosing.
Safe & Reliable – Gentle on all reef inhabitants when used as directed.
Dosage – Add 10g per 100 liters (26 gallons) of aquarium water. Use the provided measuring spoon for accuracy.
Frequency – Dose daily until magnesium levels reach the ideal range of 1250–1350 ppm, then continue with weekly supplementation.
Application – Dissolve powder in a small amount of aquarium water before adding to the tank or sump. Add near the filtration system for best dispersion.
Monitoring – Test magnesium levels regularly and adjust dosing as needed.
1KG – Ideal for medium to large reef aquariums, providing consistent, long-term supplementation.
Red Sea Reef Care Magnesium Foundation C is highly recommended for reef aquarists maintaining SPS, LPS, and other magnesium-dependent corals. Regular supplementation ensures stable magnesium levels, enabling proper uptake of calcium and carbonate for strong skeletal growth. For best results, use alongside Red Sea’s complete Reef Care program and test water parameters frequently to maintain a balanced reef ecosystem.
