Hi Jon,
A while back, I had made a DIY diffuser.  It consisted of a regular air hose, a
sponge from a whisper 300 filter, and a small tera-cota pot (sp?).  I placed the
pot upside down in the corner of my tank.  I then placed the sponge in the hole
about half way.  I believe I actually cut it down to fit in the hole.  I then
placed the air hose down into the hole along side the sponge.

With this method, I saw the CO2 bubbles suspended in the sponge, and very few
actually let go.  Hope this helps
