Made from high-purity reagents - Calcium Chloride, Sodium Bicarbonate and Magnesium Chloride with Magnesium Sulfate. Used to increase calcium carbonate and magnesium levels in marine aquarium system.
Direction: Dissolve each pack in 1 gallon of water each. Check tank's calcium and alkalinity and slowly adjust to roughly their correct ranges, e.g. calcium between 380 and 450 ppm, alkalinity between 2.5 and 4 meq/L (7-11 dKH; 125-200 ppm calcium carbonate equivalents). Individual dosing may be required to achieve their respective ranges. Check twice a week and maintain dosing according to required respective ranges.
