Pharmaceutical Grade Magnesium Sulfate Aquarium Supplement

Reef Endurance Magnesium Sulfate is a pharmaceutical-based aquarium supplement that is a fine powder that mixes crystal clear with no unwanted impurities. In reef aquaria, maintaining a proper magnesium level of 1200-1350ppm helps achieve the essential balance of calcium and alkalinity in the aquarium by preventing excess calcium carbonate precipitation. For best results, use in conjunction with Reef Endurance Magnesium Chloride for a complete balance.
