Empfohlene Konzentration im Aquarium: Calciumchlorid-2-hydrat (Teil A): 400 – 450 mg/l (ppm) Ca Natriumcarbonat/-hydrogencarbonat (Teil B): 6 – 9° dKH natriumchloridfreies Meersalz (Teil C): 1250 – 1400 mg/l Mg 375 – 400 mg/l K Tropic Marin Original Balling Components Set A/B/C is salt for supply of calcium using the Balling method. Tropic Marin Original Balling Components Set A/B/C are the 3 salt components used in the Balling method and allow an independent dosage of calcium and carbonates adapted to each individual aquarium. The three part method adds calcium chloride dihydrate (part A) and sodium carbonate/sodium 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.
