Seachem Reef Advantage Magnesium is an ammonia free concentrated (80,000 ppm) optimized blend of magnesium, chloride, and sulfate salts designed to restore depleted levels of magnesium with minimal impact on the ionic ratios found in natural seawater. Reef Advantage Magnesium helps correct magnesium deficiency, especially from the use of kalkwasser.
