Of all the trace elements found in natural sea water, iodine is associated with the widest range of effects. Iodine prevents goitre as an important component of the thyroid hormone. It also is essential for the hardening of the chitinous shell of crustaceans. Coralline algae deposit iodine in surface structures and gorgoniias deposit it in the axial skeleton. Brown algae also strongly accumulate this trace element. Benefits Highly concentrated Lugol’s solution for saltwater aquaria Essential trace element for sea dweller Exact dosages without prior dissolving Improves the adaptation to light and the colouring of anthozoa, especially of hard corals Prevents goitre at fish Is essential for the hardening of the chitinous shell of crustaceans Suitable for an aquarium stocked with marine fish, soft corals, LPS, SPS, other filter feeders and/or crustaceans Application and dosage Add one drop of Tropic Marin® Iod per 50 US-gal./200 l of aquarium system volume in the circulation flow of the system daily. If a dosage day is missed, skip that dose. Do not make up lost days by adding doses together. Iodine demand increases with aquarium population density. In heavily populated aquaria dosage may be increased up to the maximum dosage. Maximum dosage: Do not exceed a maximum dosage of two drops per 50 US-gal./200 l of aquarium system volume per day.
