Forget your bubble counter. Watch the color of the drop checker. Do this on your day off. What is your current working PSI? Try to increase it by 20% each 2 hour and watch the color of your drop checker. The color is should be somewhat yellowish by mid day, to deal with BBA issues. And fully yellow by the end of the light cycle. Watch your fish as you are doing this.
I am running a atomic co2 regulator V3, so I can't watch PSI. The only thing I can really monitor is bps. Also isn't yellow too much CO2? I thought we we are going for lime green?
