I did pretty much the same thing, I tried injecting the CO2 in from the
bottom and found that it worked much better injecting it in from the top
like the Dupla S reactor does. What I did was drill a small hole in the barb
fitting and glued 1/8" rigid air line tubing in it. I then filled the
chamber with bioballs. I have had this setup running for several months now
and it seems to be very effecient.
