Treating ich with copper. Water change question

[ReeferJoe]

Hi,

I've been treating ich with copper in my qt tank and was wondering can I put my bare hand into the water? Is there any danger of getting copper into me? I need to do water change and wasn't sure whether I should go get rubber gloves to protect myself.

Thanks,
Joe

I know most reefers don't use them but gloves are a good idea whenever putting your hands in SW
