The complete Reef Care Program is the product of years of research into the physiological demands of a reef aquarium’s SPS, LPS and Soft Corals. The program is divided into 4 distinct, but complementary, sub-programs according to biological process.

  • Reef Foundation Program

  • Algae Management Program

  • Reef Nutrition Program

  • Coral Coloration Program

  • Support

  • Provide the essential minor and trace elements that are part of the coral skeleton and soft tissue and are specifically important for SPS corals to display their natural pigments.

  • Red Sea’s research has identified 31 minor and trace elements that, in addition to the foundation elements, are present in coral’s skeleton and soft tissue. The Coral Colors supplement family divides these elements into four groups (Coral Colors A, B, C & D), with that are related by the biological functions they perform and are also associated with the production of specific color pigments in the soft tissue of stony corals. These pigments can be produced only if the specific elements required for the bio-chemical process are available in the correct concentration. All stony corals require all of these 31 elements, irrespective of the actual color the coral displays

    Supplementing to a measured uptake

    Coral colors supplements have been formulated such that the ratio of the elements in each supplement is the same as that found in the skeleton and soft tissue of corals. Our research has identified a constant ratio between each of the Coral Colors and the overall consumption of calcium, which is proportional to coral growth and metabolic activity. This provides a simple and safe method, based on a measured calcium uptake, of dosing all color supplements.

    Coral Colors A, B & C each contain a leading element (Iodine, Potassium and Iron) that is accurately measurable with Red Sea’s unique Coral Colors Pro test kits. For more advanced LPS and SPS aquariums, Coral Colors A, B & C can be dosed precisely, in accordance to the reef’s total demand for these elements.

  • Coral Coloration Program



    Coral Color A: A complex of halogens (Iodine, Bromine and Fluorine). The halogens act both as antioxidants and oxidative agents within the soft tissue and mucus layer of corals, reducing the possibility of coral bleaching. In active reef systems, these elements are depleted quickly due to their high oxidative abilities and reactivity with organic materials. Iodine and bromine are related to the pink chromo-protein (pocciloporin)

  • Coral Color B: A complex of Potassium and Boron. Potassium plays an essential role in the transportation of coral nutrients within the soft tissue (including the nutrients provided by the Zooxanthellae). Potassium and Boron significantly affect the alkalinity of a coral’s soft tissue and the formation of aragonite in its skeleton. Potassium is related to the redchromo-proteins.

  • Coral Color C: A complex of 8 “light” metals that includes Iron, Manganese, Cobalt, Copper, Aluminum, Zinc, Chrome and Nickel. These micro-elements are essential to many bio-chemical metabolic processes, including respiration, production of energy, chlorophyll and photosynthetic catalysts. C elements are related to the green/yellow chromo-proteins.
  • Coral Color D: A complex of 18 trace elements. These 18 elements (out of all the trace elements in NSW) participate in the metabolic processes inside a coral’s skeleton and soft tissue. D elements are related to the blue/purple chromo-proteins.


    All Reef Colors Supplements are available in 500ml bottles and include a measuring cup for easy dosing.
