Fin rot, what to do next

[Reaper]

Fish Bone has fin rot. He's being treated in a 2.5 gallon tank.
The question is what do I do with his regular home.
5.5 Fluval Chi
Fluorite substrate
Live plants (water wisteria, java fern, java moss, amazon sword, banana plant)
Heater.
Pitch everything? Soak everything in vinegar solution? Plants?
TIA

Hmmm, I wouldn't worry about his home. The bacteria is on him, there probably isn't much (if any) left in his home with no fins to feed off of.
