Copper is bad. If you want to run a mixed reef, you likely should start over. This could make an OK FO (without live rock) or a great fish QT tank, but I think you will be fighting copper problems for a long time to come in the tank itself. I would certainly ditch the live rock as it is tainted forever IMO. There are probably things you can run in the tank to extract enough copper to use it, but I have known tanks to get copper in them and really never gets out.jade76;124694 wrote: so..I need everyones input....what now?
