Coral Color D is a complex of 18 trace elements that promote the purple/blue colors in corals. It contains a blend of trace elements that are associated with many biological processes, one of them being the production of the purple/blue pigments in the soft tissue of corals. To ensure coral health, the ppm level of these elements must be maintained within a narrow band and therefore should only be dosed according to a measured requirement of the aquarium. For optimal results dose in proportion to the dosing of Red Sea's Foundation A (calcium/strontium) supplement.
