I made a modification of my DIY yeast+sugar system. I have an air tube
bubbling air from air pump into the close yeast+sugar+water+baking
sodas solution.

One problem I see with this setup is that the air is going to dilute the
CO2 going to your powerhead. If you are diluting the CO2 going into
your powerhead then most likely less CO2 will dissolve into the tank.
You might want to monitor your CO2 levels in your tank as part of this
experiment as well.
