Anyone know how much iodine is toxic to a reef tank or causes problems? Most people talk about too little, but my ICP shows I'm 5 times recommended. I've been dosing 5ml a week on 120 gallons of a LPS tank.
How much is too much iodine?

My Tank Thread
What ICP company, what does it say exactly, and are you dosing any?

ATI, Iodine 257.8 ug/l. Reference value is annotated as 58.1 ug/l. I've been dosing 5ml of Brightwells Iodide once a week. Looks like it's been too much. Curious what level would be considered toxic.

I don't think the toxicity level can be given as a single number because it takes at least two different primary forms in seawater (iodide and iodate) that have different toxicity and different organisms will have different thresholds for toxicity.
I think that value is not high enough to be a serious problem, but I'd stop dosing it.

Yeah, going to stop. I just got the ICP results back today. First test on the tank. I was dosing weekly for the benefit of zoanthids since it's regularly repeated that iodine doesn't hang around long in a tank.

Ok, thanks for the help. You're a great asset to the forum.
