Personally, I would wait. Give your copper time to do its job. Also remember that you want to keep that copper at a constant level for those 10 days. If not, you could have a relapse on your hands. The extra O2 will help them tremendously. My favorite piece of advise is, buy a good book. One that covers set up, health/disease, diet, maintenance, and individual care on fish/invert species. I have been in some cities to where the LFS stores had no idea what to do, or even what fish is what. Why trust some moron in a pet store who has no idea? If you don't remember what that fish needs, pull out your trusty book, and find out. When I first started I kept the book in my car, when I went on fish buying trips. Lets face it, when a national pet store chain employee(making min. wage+ commission) stands there and tells me that an Arc-eye Hawkfish is a Spotted Wrasse, why should I believe him? Well you would think that he would know what things were, wrong. He wants that quick buck, made from preying on a uninformed person.(The comparision above is very much true, I heard it about 4 weeks age!) Hope this helps you.
