In my modest experience, go find a home brew store and get champagne or wine yeast.

Put a check valve from petco for $2 on each 2L bottle (important)

Use like 4 or more 2L bottles

Shove an airstone into a powerhead

Your Co2 will rock

note:

You can also cut the impellar making it a pseudo needle wheel
