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.
1gal RO/DI + 2 Cups of Magnesium Sulfate & 5-1/4 of Magnesium Chloride
2ml/gallon of Magnesium Solution will raise magnesium by approximately 25ppm. It is not recommended to increase magnesium by more than 50ppm per day.
