I don't dose anything that I can't test for 
I dose it to maintain a level of 60ppb which is close to NSW values.

I'm not a fan of Seachem iodide. Beside their exaggerated claims, it also claims to contain secret ingredients which, IMO, I do not want to dose.
If you want to dose iodide (I'm not sure it is useful but is certainly a fine experiment), I'd pick a pure iodide product. Either DIY sodium or potassium iodide, or a brand that does not claim secret ingredients, such as ESV.

I was dosing lugols from brightwell daily and got my levels way over where they needed to be. So naturally I stopped, and I haven't noticed any difference between dosing and not to be honest.

Seachem's description makes it sound like there are secret ingredients but under Ingredients only potassium iodide is listed (at 8mg per gram). Weird.
At 8mg per gram, that means there are 4mg of potassium iodide in a 500ml bottle.
100 mg of dry potassium iodide on amazon.com goes for $21 which would make 25 bottles!
I just tried dissolving 8 grams into 500ml of RO/DI water and it dissolved easily making a double strength solution.

That bottle is 100 grams not 100 mg which is 1000 times more potent.

IMO, the inconsistencies and ridiculous claims they make at their site is a good reason to just move along to other brands and not support this misleading behavior that is detrimental to the hobby.

I've been dosing Seachem Iodide for 3 months at 2 mL into 40 gallons, every other day. (That's half the bottle's "beginner dosing" recommendation)
Without getting too detailed, I started out of desperation because all of my zoas had been in 4 month downward spiral,,, ICP test showed low Iodine,,, so figured I'd try.
Could be coincidence but a good portion of my zoa rocks are actually recovering. (Should've been picture documenting but was too lazy)
I plan to see what next ICP shows and decide whether or not to keep dosing then.
I'll probably switch to DIY if/when I run out of Seachem Iodide but, for the amount I'm dosing along with how cheap the Seachem product is,,, the money is pretty negligible.

Yes, I made two mistakes. I should have said:
"At 8mg per gram, that means there are 4 grams of potassium iodide in a 500ml bottle."
and
"100 grams of dry potassium iodide on amazon.com goes for $21 which would make 25 bottles!"
But I think it's still just 25 bottles.

FWIW, my expectation is they put an antioxidant into it, which can keep the iodide in that form in the bottle, but to claim it stays as iodide once in the reef due to an antioxidant in the additive is misleading and almost certainly incorrect.
