yeah, take out the interior tubes, put a sponge on the bottom and one on the top. for the top one you are going to have to make some type of fastener, you can probably do it with the top of the skimmer since that'll most likely be trash anyhow. take out the air hose that goes into the maxijet and there you go. if you want to use for phosban, you are going to have to downgrade to a smaller pump so that the water doesn't just push the media out, for carbon it should be fine.
