Seawater - Iodine

Iodine/Iodide is required to maintain cell functions and build up hormones and antibodies as well as to form tissue.
The very low quantity required makes conventional dispensing very difficult, as there are often excessively large changes in concentration here.

A lack of Iodine manifests itself, for example, when the polyps of large polyp scleractinia or corallimorpharia no longer expand to full size or their colours fade. However, too much, as shown by brown coloured precipitations in the tank, should also be avoided.

The invertebrates of fresh water also benefit from Iodine substitution. Frequent molting problems, a reduced willingness to reproduce and inexplicable failures may therefore be avoided especially in the ares of Central Europe with a lack of Iodine.
