Coral Colours A Supplement is a part of the complete range of complementary major, minor and trace element complexes which together provide the needs of corals.
Coral Colours D Supplement contains a blend of three trace elements that are associated with many biological processes, one of them being the production of the purple and 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 according to a measured uptake of Iodine using an Iodine test kit. An easier alternative us to dose in proportion to the dosing of Red Sea's Reef Foundation A (Calcium and Strontium) supplement.
For best results in displaying coral colours, use Red Sea's N03: P04-X
Measuring cup included.
