Tropic Marin Iodine

Tropic Marin Iodine is an iodine-potassium iodide solution in a ratio of 1:2 (Lugol's solution). Due to the fact that it contains various forms (I-, I2, I3-, I5) of iodine, this product is very suitable for addition to the aquarium.

Iodine - what for?

An additional dose of iodine has a particularly positive effect when caring for various soft corals, such as xenias and tube corals. High concentrations of the element can be found in the tissues of these animals. Gorgonians and black corals require iodine for the synthesis (= formation) of their skeleton, and the proportion of iodine contained in them can be up to 23%.

When adding iodine to saltwater aquariums, a positive effect on the color of stony corals has often been reported. Iodine is said to particularly support the formation of blue and violet colors.

Tips for using Tropic Marin Iodine

Add one drop of iodine to 200 liters of aquarium water every day. Do not add doses if you forget to add one day, for example. Stick to one drop per 200 liters of aquarium water per day. We recommend that you check the iodine level regularly using drop tests or ICP analyses. Be aware that iodine is present in a variety of different compounds in seawater and can therefore only be partially detected by tests.

If the stock is very dense and the measurements allow it, you can increase the dosage to a maximum of 2 drops per 200 liters of aquarium water per day.

Iodine is sensitive to light. It is therefore best to store it in a dark place.
