Iodine DIY

[steve 1965]

Hi I saw this and was wondering if you have ever seen this or used it for supplementing iodine with kelp in a reef tank?

Nori or seaweed also contains iodine. Problem is the quantity the fish would need to consume. You could also just use a drop or two of Lugol's Iodine each week.

I currently use RedSea elements.

Is your iodine low?

Nori and other seaweeds certainly add some iodine. I’ve not seen anyone try to maintain natural levels that way, but it may be plenty (even assuming iodine is needed, which I think is open for debate).
