I have removed the HOB skimmer from my 40B due to less than stellar performance. After a couple of days, I now notice some things floating around in the water. I believe, putting the old Whisper filter from my old FW tank could help it out. I believe the cartridge will help with mechanical filtration and the carbon might not hurt either. So, my question. How should I clean the old filter. I actually have the filter box itself pretty clean, but I wasn't sure about soaking the old motor in vinegar or bleach. Any thoughts?
