Iodine plays a major role in the hormone balance of seawater animals. Crustaceans, for example, cannot skin themselves without sufficient iodine. If you have many macro algae (e. g. Halimedia, Caulerpa or many brown algae) or disc anemones and xeniids in your aquarium, or if you filter with an algae filter, the algae can quickly consume the entire iodine concentration of the water. In this case, iodine should be supplied regularly from the outside.
Especially after the use of activated carbon and zeolites iodine has to be added to the water, as activated carbon adsorbs iodine very quickly and effectively.
The AquaCare Super Iodine is highly active due to the very effective iodine-iodide-polyiodine formula without alcohol. Under no circumstances may an overdose take place. In case of overdose, filter immediately via activated carbon. Measure the iodine concentration in the seawater aquarium regularly.
