    Details

    Calcium is required for the formation of aragonite, the skeletal material of reef-building invertebrates such as corals, clams, tube worms, and their respective allies. In reef aquaria, maintaining calcium within a range of 412 - 450 ppm will enable corals and other reef-building invertebrates to grow rapidly when all other physical and chemical requirements are met. 

    It is recommended that the calcium concentration in the aquarium be determined by using an accurate test kit prior to supplementing. Do not add this product directly to an aquarium containing live animals without first diluting in water as directed.

    Instructions and Guidelines:
    Basic: Dissolve 2 grams (~1/2 teaspoon) of product per 20 US-gallons of aquarium water in 8-fl. oz. of fresh water; add every other day or as needed to maintain the calcium concentration within a range of 412 - 450 ppm. When used in this fashion, 400 g treats up to 4,000 US-gallons (15,142 L). 

    Advanced: Create a stock solution by dissolving 10 grams (~5 teaspoons) of Calcion-P in 8-fl. oz. of fresh water (preferably purified); each ml of the solution will increase the calcium concentration ("Ca2+") in 1 US-gallon (3.785 L) of water by 2.50 ppm. [Reference: Each g of Calcion-P will increase the Ca2+ in 1 US-gallon (3.785 L) of water by 95 ppm.] If initial Ca2+ in the aquarium is below 412 ppm, add stock solution at maximum rate of 10 ml per 20 US-gallons daily until desired concentration is attained, then dose daily or weekly as needed (see below). Maintain Ca2+ within a range of +/-10 ppm. Once desired Ca2+ has been acquired, measure aquarium's Ca2+ at the same time each day over a one-to-two-week period to determine the daily rate of calcium uptake (i.e. the decrease in calcium). To determine daily dosing rate (preferable to weekly dosing): estimate volume of water in entire aquarium system (US-gal.); divide the daily decrease in Ca2+ by 2.50; multiply this number by volume of water in system to obtain daily ml of stock solution required to maintain stable Ca2+.

    Caution:
    Keep out of reach of children. Not for human consumption.
