Just found something that chelates copper out of an aquarium.

E.D.T.A. (Ethylene Diamine Tetra Acidic Acid)

Have to do more research on it but it was mentioned in an article I stumbled across. It inactivates the copper to make it safe. Just thought I'd mention it in case Liz might want to check it out.
