I'm done with my 10g hosp tank (fish died). I know to disinfect everything (bleach wipe or soak or vinegar ?), throw away filter media (Penguin biowheel 200); bleach inside of filter too ?. Do I replace the wheel too or keep for next hospital set up ? What about the the rock and handful of gravel I had in there ? Those are porous so can I just use vinegar instead of bleach ? Or alcohol ? :huh: Thanks.
