Copper power green is mainly for Ich problems.
Some research needs done , maracyn#2 is much more affective for fin rot. There are gram positive and gram negative infections. You must address the “root” cause. If truly fin rot maracyn #2 for gram negative infections is best ! What stage is the fin rot in 1,2,3or4. Yes there are stages and treatment adjusted to stage.
You must separate infective fish , a quarantine tank , never treat home tank with the other fish or turtle. Wont hurt them but one never treats a home tank treat the sick fish. Home tank can be fully cleaned , media too ( replace media best ) ! Any treatment will kill all your good beneficial bacteria along with killing the bad bacteria. This is also a good time to have a properly sized UV "sterilizer" to remove the bad bacteria not a UV "clarifier" but sterilizer.
If truly fin rot maracyn #2 for gram negative infections is best !
PS: You actually have two problems the scales falling off is another problem. Melafix can help that , different from fin rot ! Normally due to keeping them in wrong water parameters. Trutles are warm water and goldfish are cool water fish and need undectable parameters. Yes could and does work in same tank but the goldfish will never be truly healthy.
