you could also always do something like this. these are the small ones but they make some pretty big ones out there.
sorry for them being labled but these were some pics i took the other day for the thread listed in my sig and i figured they might help. these are floss filters so you load them with floss and carbon and they work just like a sponge filter. there about a 1/3 of the cost as a sponge filter.
these are rated at about 5-10g while the triangles in the last pics backround are rated at 20g. drfosters and smith and petsolution have these al the way up to about 75g.
there just a little more pricey than what these are http://www.petsolutions.com/Triple-Flow-Corner-Filters+I10813405+C19.aspx
