Hi everyone and thanks in advance once gain. I have a HOB filter that is currently on a 20 gallon tank that I am treating for ich. if I clean it very good with bleach will it be safe to move it over to a 40 gallon. ( the HOB filter is an aqua clear 70 )

Once the Ick clears up, allow the filter to run two or three weeks, then transfer it the other tank.
No need to sterilize it & the media will remain cycled.
