Regular use of Preis–Iodine will improve the colours and boost growth, especially in the case of stone corals.
Preis–Iodine also promotes the development of the chitin exoskeleton of crustaceans and corrects thyroid deficiency in fish. We particularly recommend adding Preis–Iodine regularly in the case of particular soft corals such as Xeniidae and higher forms of algae. Ideally, the product should be added after the light phase.
