- Basic: Shake product well before using. Add 5 ml (1 capful) of product per 25 US-gallons of aquarium water every other day or as needed to maintain the calcium concentration within a range of 412 - 450 ppm. When used in this fashion, 250 ml treats up to 1,250 US-gallons (4,732 L). When used in equal amounts with Reef Cōde B, the calcium and carbonates being added are in the same ratio found in natural seawater. Do not mix products in the same container; this will cause the active components to precipitate and become ineffective. Allow 60 seconds to pass between dosing Reef Cōde A and B. Advanced: Determine the calcium concentration in the aquarium using an accurate test kit before supplementing. Shake this product well before each use. Each ml of Brightwell Aquatics Reef Cōde A will increase the concentration of calcium (“[Ca2+]”) in 1 US-gallon (3.785 L) of water by approximately 16 ppm. If the initial [Ca2+] in the aquarium is below 412 ppm, add this product at the maximum rate of 5 ml per 10 US-gallons daily until the desired calcium concentration is attained, then dose daily or weekly as needed (see below). Note that each aquarium has different requirements for calcium and carbonates (which largely constitute Alkalinity or Buffering Capacity, hence pH-stability); therefore, it is not uncommon for unequal amounts of Reef Cōde A and B to be required for obtaining and maintaining the desired calcium concentration and alkalinity. To determine the daily dosing rate for calcium maintenance: estimate the volume of water in the entire aquarium system; divide the daily decrease in [Ca2+] by 16; multiply this number by the volume of water in the system to get the daily dosage required (ml) to maintain a stable [Ca2+]. Guaranteed Analysis: Calcium (min) 1,774 mg/oz. (60,000 ppm), Magnesium (min) 42 mg/oz. (1,500 ppm), Strontium (min) 36 mg/oz. (1,200 ppm) Caution: May cause eye or skin irritation. Flush with water for 15 minutes if in eyes, seek medical attention if irritation persists. Keep out of reach of children. Not for human consumption.
