Tropic Marin Original Balling Refill Set 3x5L
Corals and other invertebrates use calcium from the seawater in which they live. While there is an inexhaustible supply of calcium in the ocean, in the marine aquarium, calcium and alkalinity are depleted quickly. To support the healthy, natural growth of corals, a balanced calcium supplementation is essential. Tropic Marin Original Balling Refill Set consists of three different salt mixtures (A, B, C) that get dissolved in water to refill the three bottles of Tropic Marin Original Balling Liquid Set. This saves packaging and transport.
