The Tropic Marin Original Balling Liquid Set consists of three solutions A, B and C according to the well-known Balling method and can be used immediately. The three-part 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.
