Red Sea RCP Reef Colors A Supplement 16.9-oz

IODINE+ Supplement is part of Red Sea’s complete range of major, minor, and trace element complexes that together fulfill the essential needs of corals.

Red Sea Products supplement provides Iodine along with other halogens that play a vital role in numerous biological processes, including the development of pink pigments in coral soft tissue. Acting as both antioxidants and oxidative agents, halogens help strengthen the coral’s soft tissue and mucus layer, thereby lowering the risk of coral bleaching.

In active reef aquariums, these elements are rapidly depleted and aquarium water treatments of their strong oxidative properties and quick reactions with organic materials. Among them, Iodine and Bromine are directly linked to enhancing the pink chromoprotein Pocciloporin, which brings out vibrant coral coloration.

For the most striking coral color display, IODINE is best used alongside Red Sea’s NO3 and PO4–X. Together, they promote healthy coral growth, improved pigmentation, and a more resilient reef system.
