I have a 65 gal planted fish tank. CO2 injection system. I'm running 12 bbs in my tank. My starting PH is 7.2 and after 8 hrs of running the PH is 7.0. My KD is 4. That means I'm only getting 12 PPM of CO2. I don't know why the PH doesn't go down. I know it should be higher but with out open my bubble counter wide open, how can I achieve a 22 + CO2 PPM? What bbs should I be setting?
