Magnesium is required to regulate the balance between calcium and carbonate when forming aragonite. Stronger and more economical than liquid supplements, Magnesion-P is formulated by marine scientists and contains 43% magnesium by dry weight.
Specifications Package Size TREATS UP TO 2,400 GAL.
Aquarium Type MARINE
Instructions Basic: Dissolve 2.5 grams (� 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 magnesium concentration within a range of 1,290 - 1,320 ppm.
Advanced: Create a stock solution by dissolving 20 grams (4 teaspoons) of Magnesion-P in 8-fl. oz. of fresh water (preferably purified); each ml of the solution will increase magnesium concentration (�[Mg2+]�) in 1 US-gallon (3.785 L) of water by 6.0 ppm. [Reference: Each g of Magnesion-P will increase the [Mg2+] in 1 US-gallon (3.785 L) of water by 114.4 ppm.] If initial [Mg2+] in the aquarium is below 1,288 ppm, add stock solution at maximum rate of 10 ml per 20 US-gallons daily until desired [Mg2+] is attained, then dose daily or weekly as needed. Maintain [Mg2+] within a range of +/-10 ppm.
Once desired [Mg2+] has been acquired, measure aquarium's [Mg2+] at the same time each day over a 1-2 week period to determine the daily rate of magnesium uptake (i.e. the decrease in magnesium). To determine daily dosing rate (preferable to weekly dosing): estimate volume of water in entire aquarium system (US-gal.); divide the daily decrease in [Mg2+] by 6.0; multiply this number by volume of water in system to obtain daily ml of stock solution required to maintain stable [Mg2+].
Caution: Keep out of reach of children. Not for human consumption.
