Instructions and Guidelines

Basic Instructions and Guidelines: Add 20 grams per 8-fl. oz. of purified water in a clean mixing container and stir to dissolve; dose the resultant solution to the aquarium system as required to maintain the calcium concentration within a range of 412 - 450 ppm.

Advanced Instructions and Guidelines: Create a stock solution by dissolving 35 grams of Reef Code A-P in 8-fl. oz. of purified fresh water; each ml of the solution will increase the calcium concentration (“[Ca2+]”) in 1 US-gallon (3.785 L) of water by ~10 ppm. [Reference: Each g of REEF CŌDE A-P will increase the [Ca2+] in 1 US-gallon (3.785 L) of water by ~87 ppm.] If initial [Ca2+] in the aquarium is below 412 ppm, add stock sol’n 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: estimate volume of water in entire aquarium system (US-gal.); divide the daily decrease in [Ca2+] by 10; multiply this number by volume of water in system to obtain daily ml of stock sol’n required to maintain stable [Ca2+]. Dose system as required to maintain desired calcium and alkalinity (using Reef Code B-P) values. Do not mix solutions together; this will cause the active components to precipitate and become ineffective. May be mixed individually in large containers and dosed with a drip- or automated-dosing system; ensure that solutions are entering the system in different areas to prevent precipitation. If dosing manually, allow at least 5 minutes to pass between dosing Reef Code A-P and B-P solutions.
