Advanced calcium supplement for marine aquariumsMakes it easy to rapidly adjust calcium levels in aquariumsHelps maintain optimum water quality for growth of aquarium inhabitantsJulian Sprung's Reef Formula Calcium Concentrate rapidly raises the calcium concentration when the alkalinity level is already high. Also simultaneously lowers the alkalinity level, bringing both closer to a natural seawater ratio. When the calcium and alkalinity levels are properly balanced, stop using Calcium Concentrate, and continue using a balanced ion supplement such as Kalkwasser or C-Balance, which maintain alkalinity in addition to calcium concentration. Phosphate-, nitrate- and silicate-free. For marine aquariums. Add 1 tsp per 10 gallons.Please click on "More Information" for dosage, ingredients, and more.
