I'm not a fan of bio balls. Your foam pads do the same job as bio balls. You might need to cut some foam off one of the filter pads to make room for ceramic rings. Come to think of it I'm pretty sure your foam pads serve the same purpose as bio balls and rings. Maybe just add some carbon to that filter. You said your running 2 filters?Just make sure you clean all your media in tank water no matter what you use. Carbon will need replaced at least once a month. I wouldn't just fill the filter with rings or bio balls they won't trap debris like the foam filters will.
