tap water prob. contains more copper then any fish food and people use previous freshwater tanks for new saltwater tanks all the time.
i would say if it was a copper based medication in the tank at anytime i would be iffy on re-using it for a saltwater tank. even QT tanks should be used only for a QT for this reason ( as well as who knows what diseases could linger, but a bleach rinse solution should handle that. )
i believe salifert makes a copper test, and although they are a good company im unsure of how effective this copper test is.
