Hi Skiltrip,
I know of copper safe, and it's more or less used as a preventative as opposed to a treatment (it does work on some ectoparasites though). Although it will have a small impact on the ich, I haven't had much success with copper safe and ich, not enough to get rid of it completely. Mardel Maracide works well for ich I've found, usually getting completely rid of it within 5-10 (depending on how bad the infestation is). You'll want to make sure you remove all the copper before you use another "anti-parasite" treatment, do this by small water changes over the next few days. Might be a good idea to pick up a copper test from the LFS. I don't know how effective carbon is at removing copper, maybe someone else knows if a brand new carbon will be able to pull it out?
