Tropic Marin® Block Iodine is a concentrated solution for adding iodine, fluorine, bromine, and selenium if there are deficits in the aquarium.
The halogen iodine, fluorine, and bromine are incorporated in organic and inorganic skeletons and strengthen them. Iodine is essential for the light acclimatization of corals. Selenium acts as protection against oxygen radicals.
The Tropic Marin® Block System uses an indicator element to dose-related trace elements that are consumed in the same ratio. Often, their levels are below the detection limit of the analyzing meters and cannot be measured correctly.
