Coral Colors D Supplement is part of the complete range of complementary major, minor and trace element complexes which together provide the needs of corals.
These 18 elements (out of all the trace elements in NSW) participate in the metabolic processes inside a coral’s skeleton and soft tissue, one of them being the production of the purple/blue pigments in the soft tissue of corals.
For best results in displaying coral colors use Red Sea’s NO3: PO4- X.
