Pics would help. I've never had to treat for fin rot so someone else can hopefully help. First thing is that whatever you treat with it either has to be compatible with Cupramine or remove all Cupramine before treatment. If I ever see any hints of bacterial issues in QT while treating with Cupramine I use Maracyn II. That can also be used while treating with Prazipro. Are you sure it is fin rot? Flukes can damage fins to make it look like fin rot.
I'm sure you have already checked the ammonia levels, as this is a huge issue in QT's. While treating with Cupramine you will get false high readings of ammonia with some test kits. I use Seachem's ammonia alert badge on my QT's.
