Red Sea Coral Trace Colours B (Potassium), K and Trace Elements promotes the natural red colours in corals.

These elements work together to promote and support the alkalinity of coral's soft tissue and formation of a healthy, strong skeleton. They are naturally depleted from the water, and therefore regular testing and restoration of these elements is imperative to ensure levels are maintained.

Red pigments are produced and strengthened too, and this will allow the glorious reds and pink colours of your corals to shine with health.
