The sponge I use just as extra bio media. I forget what brand it was, Fluval or Filstar or something, but it fit exactly into the slot. Didn't have to trim it down or anything. I figure it's always good to have extra surface area for the bacteria.
Right now i have the old sponge from my whisper 20 in one of the extra slots...........i put it there during the tranfer for the bacteria.........ill look into the ones that you mentioned.........
