do they make a sponge filter gor maxijets?

[loyalty]

i have a 900 feeding my HoB fuge, and i'm finding a lot of uneaten flake in my chaeto. I'm thinking a sponge filter on the intake of the maxi would keep funk from building up in the fuge
TIA

There is a 2 pack replacement sponge for the Seaclone that comes with another plastic frame. There's one here, listed as a sponge prefilter. others should have it also http://www.marineandreef.com/shoppro/aquarium_systems.html, the 2 pack sponge is last on this list, http://www.drsfostersmith.com/Product/prod_display.cfm?pcatid=4609&rel=1
