Reef Endurance Calcium Chloride is a pharmaceutical-based aquarium supplement that mixes crystal clear with no unwanted impurities. In reef aquaria, maintaining calcium within a range of 412-450ppm will enable corals and other reef-building invertebrates to proliferate. For best results, use in conjunction with Reef Endurance Sodium bicarbonate or Soda Ash as a two-part balanced regimen.
1gal RO/DI + 2-1/2 Cups of Calcium Chloride
1ml/gallon of Calcium Chloride Solution will raise calcium by approximately 10ppm. It is not recommended to increase calcium by more than 50ppm per day.
