Calcium Pronto is a fast-dissolving pure, dry calcium chloride that makes it easy and economical to rapidly raise the calcium ion concentration in aquariums. Supplemental calcium is required for reef aquariums because corals, clams, snails, tube worms, and calcareous algae extract calcium carbonate from the water. Use a calcium test kit to measure the calcium concentration in the aquarium. It should be maintained between 380 and 450 ppm.
