Tropic Marin Iodine 50 ml

Features:

Lugol´s solution for saltwater aquaria

Of all the trace elements found in natural sea water, iodine is associated with the widest range of effects. Iodine prevents goiter as an important component of the thyroid hormone. It also is essential for the hardening of the chitinous exoskeleton of crustaceans. Coralline red algae deposit iodine in surface structures and gorgoniias deposit it in the axial skeleton.

The natural replenishment with trace elements is not guaranteed in a saltwater aquarium, iodine should be added to a marine aquarium on a regular basis. Experiments clearly show that Tropic Marin^® IOD improves the adaptation to light and the coloring of anthozoa, especially of hard corals. Tropic Marin^® IOD contains iodine in its most effective form, as elementary I₂ in a Lugol´s solution.

Benefits:

How to use:

Add one drop of Tropic Marin^® IOD per 200 l / 50 US gallons of aquarium system water 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 below.

Maximum dosage: Do not exceed a maximum dosage of two drops per 50 gallons of aquarium system water volume per day.

Tropic Marin^® IOD has to be stored dark.

Pack Size

50 ml / 1.7 fl.oz. bottle, article 24304. This is the only container size Tropic Marin publish for Iod, so there is no larger economy bottle to wait for.

It is dosed by the drop rather than by volume, which is the point of buying a Lugol’s solution rather than mixing one: one drop per 200 l (50 US-gal.) of system volume daily, and never more than two drops per 200 l per day. At that rate a 50 ml bottle is a long-running bottle even on a large system.

Iodine is unstable in solution, which is why it has to be replaced regularly and why the bottle has to be stored in the dark. A missed day is skipped, not made up — do not add two days’ doses together.
