I use either Chemi-pure, purigen or polyfilter pads on different tanks .

Either way I think for a sponge filter , A polyfilter pad might be what you are looking for . I have found that current does NOT have to go through it , in order for it to work but there has to be some water circulation in the immediate area and sponge will work.

You just cut the pad into small pieces and change when it turns dark brown .
