Red Sea’s Coral Colors A, B, C & D are specialized supplements formulated with 31 essential minor and trace elements that naturally occur within the skeletons and soft tissues of corals. Each Red Sea Products supplement is carefully grouped according to its biological role, directly supporting the development of specific color pigments in stony corals. For example, these trace aquarium water treatments elements enhance the production of pink, red, green/yellow, and purple/blue pigments, helping corals express their natural vibrancy and health. Importantly, all 31 trace elements for aquarium water treatments are vital for every stony coral species, regardless of the particular coloration the coral may display in the aquarium.
By replenishing these critical elements, Coral Colors A, B, C & D promote both skeletal structure and rich tissue pigmentation. For the most effective results in achieving brilliant, long-lasting coral coloration, Red Sea recommends combining these supplements with NO3:PO4-X, an integral part of the complete Reef Care Program, which ensures balanced nutrient levels and optimal coral growth conditions.
