Trace Colours C Supplement is a part of the complete range of complementary major, minor and trace element complexes which together provide the needs of corals.

A complex of eight “light” metals that includes iron, manganese, cobalt, copper, aluminum, zinc, chrome and nickel.

These micro-elements are essential for many bio-chemical metabolic processes, including respiration, production of energy, chlorophyll and photosynthetic catalysts. C elements are related to the green/yellow chromo-proteins.

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

1ml will raise the Iron levels of 100L by 0.01 ppm
