Seachem Reef Advantage Magnesium | Ammonia-Free Reef Supplement

Seachem Reef Advantage Magnesium – Ionically Balanced Magnesium Supplement

Seachem Reef Advantage Magnesium is a concentrated (80,000 ppm), optimized blend of magnesium, chloride, and sulfate salts designed to restore depleted magnesium levels in reef aquariums. Magnesium is critical for the stabilization of carbonate alkalinity and the formation of coral skeletons. Unlike many liquid supplements, Reef Advantage Magnesium contains no ammonia, a common contaminant that can stress sensitive reef inhabitants. Maintaining proper levels (1,200–1,350 mg/L) prevents the precipitation of calcium and carbonates, ensuring these essential elements remain bio-available for your corals.

Essential Stability for High-Growth Reefs

Reef Advantage Magnesium provides a professional-grade solution for preventing ionic imbalance and supporting long-term coral health.

• Ammonia-Free Purity: The only major magnesium supplement guaranteed to contain no ammonia, protecting your fish and corals during high-volume dosing.

• Optimized Salt Blend: Uses a specific ratio of chloride and sulfate salts to mimic natural seawater, ensuring minimal impact on the aquarium's overall ionic balance.

• Prevents pH Depression: Corrects severely depleted levels (below 800 mg/L) that can lead to chronically low pH and an inability to maintain stable calcium levels.

• Combats "Kalkwasser Precipitation": Specifically designed to replenish magnesium lost when using kalkwasser or overdosing carbonate additives.

• Highly Concentrated Powder: Available in multiple sizes (300g, 600g, 1.2kg, 2.2kg, and 4kg), offering a cost-effective alternative to liquid supplements for large systems.

FAQ Section: Common Questions

• How do I dose Seachem Reef Advantage Magnesium? Beginner: Use 5 g (1 level teaspoon) per 80 L (20 gallons) twice a week. Dissolve in at least 250 mL of freshwater before adding to the tank.

• Can I mix this with my alkalinity buffer? No. Do not directly mix with any carbonate supplement as precipitation will occur. It is best to add magnesium and carbonate additives on alternate days or at least 30 minutes apart.

• What is the maximum daily dose? Do not exceed 25 g per 80 L (20 gallons) in a single day, as excess magnesium may enhance the loss of carbonate alkalinity.
