  • Red Sea Reef colors supplements have been formulated such that the ratio of the elements in each supplement is the same as that found in the skeleton and soft tissue of corals. Our research has identified a constant ratio between each of the Reef Colors and the overall consumption of calcium, which is proportional to coral growth and metabolic activity. This provides a simple and safe method, based on a measured calcium uptake, of dosing all color supplements.
