Red Sea Trace Colors ABCD 4 pack provides hobbyists of all levels the opportunity control and enhance the growth and coloration of corals.

• Red Sea Trace Colors A (Iodine/Halogens) 100 mL - promotes pink colors
• Red Sea Trace Colors B (Potassium) - 100 mL promotes red colors
• Red Sea Trace Colors C (Iron/Complementary Trace Elements) 100 mL - promotes green/yellow colors
• Red Sea Trace Colors D (Trace Element Complex) 100 mL - promotes purple/blue colors

Red Sea’s research into the metabolic demand of SPS, LPS & soft corals has identified 31 minor and trace elements that in addition to the foundation elements are present in the skeleton and soft tissue of all corals. These elements are known as important bio-catalysts in thousands of metabolic processes in marine organisms and therefore must be readily available in all reef aquariums. Many of them, however, become toxic in concentrations above the levels found in natural seawater and therefore their correct dosage is crucial to the long term success of any reef aquarium.

Our research has identified 4 distinct groups of elements with similar biological functions as well as a direct connection to specific coral pigments that enabled the division of the 31 elements into the 4 supplements Coral Colors A, B, C & D. Coral Colors supplements have been formulated such that the ratio of the elements in each supplement is the same as are found in the combined coral skeleton and soft tissue.

All of the Coral Colors should be supplemented regularly to all LPS and SPS aquariums without connection to the colors of the specifi c corals or whether the water parameters (levels of foundation elements and algae nutrients) are set for enhanced coloration or accelerated growth.

Enhanced Coloration

In reef aquariums corals often have higher than natural populations of Zooxanthellae algae that give a deep brown tint obscuring the natural vivid pigments of the corals. Lowering the Zooxanthellae populations by fi ne control of algae nutrients (such as with Red Sea’s NO3:PO4-X) will remove the brownish tint and induce the production of pigments (chromoproteins) that protect the delicate inner layers of the coral soft tissue from intense UV radiation, similar to the tanning of human skin when exposed to direct sunlight.

Our research has shown that the pigments can only be produced by the soft tissue of the coral if the specific elements required for the bio-chemical process are available in the correct concentration. Each of the natural pink, red, green/yellow & blue/purple pigments are connected with specific elements that correlate with the elemental grouping of the Coral Colors A, B, C & D.

Dosing by total elemental demand

Coral Colors A, B & C each contain a leading element (Iodine, Potassium & Iron) that is accurately measurable with Red Sea’s unique Coral Colors Pro test kits enabling the replenishment of each of these supplements according to the total demand of the reef.

Dosing by calcium (coral growth) demand

Our research also 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. Therefore, by measuring the uptake of calcium by the corals we are able to replenish all of the elements that have definitely been depleted from the water by the corals, without the danger of reaching toxic levels. This method of dosing should be used for supplementing Coral Colors D and can be applied successfully to Coral Colors A, B, & C.
