A - halogens I2, Br, F2, B - potassium and boron, C - Fe and 7 complementary metals, D - 18 bioactive trace elements. The elements in each supplement are related by their biological function and are associated with the production of specific color pigments pink, red, green/yellow and purple/blue in the soft tissue of stony corals. All 31 elements are required by all stony corals irrespective of the actual color the coral displays. For best results in displaying coral colors use Red Sea's NO3:PO4-X as part of the complete Reef Care program. Coral Colors A, B, C and D should only be dosed according to a measured requirement of the aquarium.
