The Tropic Marin® Original Balling Refill Set is for refilling the Tropic Marin® Original Balling Liquid Set by dissolving each bag in 1.32 US-gal./ 5 l water WITHOUT WEIGHING.
The three part Balling method adds calcium chloride dihydrate (part A) and sodium carbonate/bicarbonate (part B), while the addition of sodium chloride free sea salt (part C) maintains the crucial ionic balance in the aquarium water. This balanced calcium dosage creates the best conditions for good growth of corals and coralline algae and avoids the inevitable decrease of important elements seen in two part methods.
1 liter/0.26 US Gal. Original Balling Liquid A, B and Ccontain 20,000 mg of calcium and 2800 °dH (= 52 g/1,8 ounces calcium carbonate). Natural seawater has a calcium level of approximately 410 mg/l and an alkalinity of 6,5 °dH. In aquariums which are high in alkalinity and low in calcium the calcium concentration should be adjusted at first by only adding solution A.
First measure the carbonate hardness and the calcium content of the water. Calculate the total system water volume, taking care to take into account the volume of live rock, external filters and sump tanks present. The addition of 1 fl. oz. / 28 ml of each solution will raise the calcium level of 10 US-Gal. / 35 l by approximately 15 ppm. Maximum recommended dose: 2 fl. oz. / 60 ml per 10 US-gal. / 35 l of aquarium water per day.
