You wouldn't by chance be running a filter system with a sump would you? 
If you are I have a really easy way to make one and it is cheap too!

Just get 3 - 4' of 1" - 2" Corrugated tubing and place it after your pump.
The CO2 enters the intake of the pump and gets broken into very small
bubbles which get caught in the corrugations in the tubing. So you
shouldn't get any bubbles going into the tank at all. Works like a charm
for me.

If you don't have a sump you still may be able to adapt the setup.
