I was perusing through an essential oil dealer and noticed that they have the essential oil for Seaweed (30%, from France, Lamanaria digitata). $37 for 15mL!
Now this is rather expensive I noticed, but would this contain large quantities of Iodine? Or just trace amounts that would a pain to extract anyway? It would have to contain extremely high amounts to be cost effective, so this probably isn't viable, but thought I would share it anyway.

I doubt that oil would contain a worthwhile amount of iodine.
What is then,a good source of Idione(either product
or synthesis)?

Er...how difficult is it to get iodine? Lugol's is extremely common stuff.
Potassium or sodium iodide !

Lugol's is 10% potassium iodide, 5% iodine.
I've searched high and low for a UK source of Lugols's solution with no success. Maybe it's only popular in the US.

Mastery is based on the understanding and practice of technique.
Iodine is used in reef tanks. You should be able to find some KI solutions in a store that specializes in reef tanks.
