No don't ditch anything as of yet run carbon make sure all the Cu is out. Since you have a hanna checker I would wait a few days then retry copper treatment and make sure levels don't exceed the aforementioned acceptable levels. I think the big water change should help also run. Also run carbon.
It's like you are starting over with Cooper treatments but this time you are more informed. Did you order the chelated copper or are you sticking with cupramine?
Already ordered chelated copper.
I thought the copper from my current QT wouldn't leave my filter / sand / air stone regardless of what I did.
