Obviously you don't want to remove the filter foam. Do you think you would have some room to squeeze a bit of floss in. I had an interpet internal, single block foam. I just cut about an inch off the block and filled the gap with floss. Also, when your Carbon is exhausted, run the floss instead. So much cheaper. You only need carbon for med and odour removal....
