wow yes, that's a lot of dead fish. Please stop using copper, it's very dangerous for fish and not a good treatment for ick. Use hyposalinity instead which is easy on the fish.
I suspect the copper killed the fish rather than the ick.
You should really leave your main tank fishless for 2 months and then do a proper quarantine of 6 weeks with hyposalinity and that should work better. I had 100% sucess with hyposalinity treating ick, and I always combien hyposalinity with Seachem Paraguard and I never lost a fish in quarantine. ON top of that, I use fully cured liverock (no coral) in the QT with the hyposalinity and Paraguard and never had a trace of ammonia. Paraguard does not destroy the biofilter, nor will hyposalinity so filtration remain very good with liverock.
