I have two filters that I need to disinfect. I am not sure how to go about this by using chemicals, without ruining them. I would like to make sure I get them completely clean before ever using them again. I also have a glass heater and a ceramic heater, some rocks, and a few silk betta plants. Is bleach safe to use on those last items? Or should I use vinegar? My fish had a bacterial infection as far as I know, I never saw anything parasitic. However I'd like to make sure I completely kill any harmful bacteria from these items before reusing them. I figure for the tanks I can just let a bleach or vinegar solution sit overnight.
