Iodine - what for?

Especially when caring for different soft corals, such as xenia, an additional dosage of iodine has a positive effect. High concentrations of the element can be found in the tissue of these animals. Gorgonians and black corals require iodine for the synthesis (=formation) of their skeleton, and the proportion of iodine contained therein can be up to 23%.

When iodine is added to reef tanks, a positive effect on the coloration of stony corals has often been reported. Iodine is said to particularly support the formation of blue and violet colors.
