Do your corals like iodine supplement?

[SouL_Shaker]

I started dosing KZ iodine and potassium supplement for half capacity of aquarium daily... Because I hardly change water. And corals lose their color if I don't.

May I ask , which corals like iodine supplement in aquariums ?

Dosing iodine without testing is not advised.

I personally think very few of the creatures we keep benefit from supplemental iodine. Certain specialized gorgonia have a demonstrated use for iodine as do some black corals, but not most things you'd have in a tank.

I dosed it for many years, then stopped and saw no difference.

Test is not available in my country. Because companies can not sell iodine tests so they are not available for purchase.

Personally I have been dosing kz potassium + iodine supplement for a week. My corals have been happier than they were before. Their body has been bigger than it was before.

I don't know if what you observe will last or is actually from the product, but that product contains a variety of different ingredients in addition to iodine which might contribute to what you are observing:

"Inorganic and organic iodide, bromine, potassium and fluorine"

Is it harmful ?

Not likely, but it isn't clear what organics they may be using. The other things are not harmful at appropriate levels. :)
