I think the bioballs would help a bit. I think HeyPK told me that as the co2 goes out of the bubble O and N go in it. So you may still have pretty good absorption.
I have a nipple at the top of my reactor with a piece of airline tubing terminated by an air valve. I open the air valve every couple of days to bleed out the gas.
What is important is your CO2 ppm readings. Are you getting 20 ppm CO2? If so, you don't have a problem.
The Eheim diffuser works well up to 75 gallons.
