This one sounds simple but would love advice. I have an old pro clean wet/dry filter. Now I want to get away from bio balls. I do not have room for a fuge. So what I'm asking I guess is what can I use in place of bio balls in the wet/dry ? (what media ) ? Or how can I revamp the old wet/dry ? I also have a canister not in use (hear they are a pia .any advice would be great, thanks all in advance.
