Did either of you go to college and are marine biologist. They took the classes and passed so I think they are a bit more qualified. It was their decision to kill the tank to benifit the fish. Better alive and cured than dead. If anything they looked outside the copper cure all box and treated the fish and were honest about it. Even Martin Moe states in his book that when all else fails..start the tank over. Sorry you can't look in any other direction other than tank transfer and copper. Sometimes they don't work.
