Copper treatment with UV and protein skimmer?

[marinenut]

I've done a search on this, but couldn't come up with anything. I was wondering if I should keep my UV sterilizer on or off while I'm doing a copper treatment? I've heard that I need to keep the protein skimmer off, because it will cause a toxic copper concentration to build. I'm using Mardel Coppersafe, which apparently is chelated copper sulfate.
Thanks.
By the way, I have a FO tank.

Copper should be fine, but you do need to turn it off for antibiotic treatment.
