Seachem Reef Advantage Magnesium – 2.2 lbs

The 2.2 pound container of Seachem Reef Advantage Magnesium is a concentrated (80,000ppm) optimized blend of magnesium chloride and sulfate salts, designed to restore depleted levels of magnesium with minimal impact to the ionic ratios found in natural seawater. Seachem Reef Advantage Magnesium contains no ammonia, which is a common contaminant found in nearly every liquid magnesium supplement of the market. Severely depleted levels of magnesium (below 80 mg/L) can sharply drop pH levels as well as the render the tank unable to maintain proper magnesium levels. Magnesium depletion is commonly associated with the use of kalkwasser and low levels of salt mix.
