In addition to magnesium, PREIS MAGNESIUMIODINE CONCENTRATE contains iodine which is a vital trace-element.
The iodine concentration of natural seawater is about 0.06mg/ l. Iodine tends to become depleted very quickly, and depletion is furthered by heavy scumming and strongillumination.

Iodine must therefore be regularly replaced, since invertebrates and coral will grow poorly when suffering from iodine deficiency. More highly developed algae will completely cease to grow while the formation of smear algae will be enhanced.

Iodine has a disinfectant effect and thus helps in a natural way to keep your coral fish healthy and resistant to disease.
In new imports and after medical treatment PREIS MAGNESIUMIODINE CONCENTRATE enhances the natural healing process.
