I bought the HOB filter from petco. The sponge is pretty tiny. Can I add a part of a filter sock in the slot where I'm removing the charcoal filter or any other suggestions? Can I just run the filter or do I also need a powerhead? From what I understand if I use my powerhead in a diseased QT then I can't reuse it in my DT. Please advise.
