I too have found that sponge filters are just about the best thing going in
plant tank filtration. You achieve water movement, minimal turbulence and
the very presence of the filter acts as a CO2 reactor. To maximize the
output, hoeever,it is possible with a DIY unit to insert the output hose of
the CO2 bottle into the top of the tube of the sponge filter down the tube
into the sponge. I'm not sure how that will translate into bottled CO2 but
if feasible,a sponge filter makes a great reactor. I'm a very low tech type
who believes if it works and its cheap, you're damn lucky. There's an
additional plus that beats  all! I've had much luck raising fish fry on all
the infusorions in the filters.
Also, these filters don't suck the babies in and need minimal maintenance.
Good luck to you!
