hmmm? pics would help!
This might be of interest, its my way of aerating my DWC. I call it SRDWC! Maybe it'll bring some new ideas to the table. Check out my video on Super Recirculating Deep Water Culture http://youtu.be/2nd-p8uyxeA

Cool vid dvlhaze... cool concept!!
I hope you dont take it the wrong way, but your venturi is just slightly out of tune. It would be much more efficient if instead on a T style terminal air intake hose, if it would go into the pump fitting, make a 90º angle with the hose hole pointing in the direction of the water flux. This massively increases negative pressure and air diffusion.
The way you have it now certainly works, but the negative pressure is reduced by the air column "smashing" against the water current. Slightly deeper inside and angled 90º would eliminate any counter pressure.
