Unless it's just coincidence but while watching tv tonight i've observed that my co2 is still running. I do understand the concept of a ph set point and controller to keep co2 / ph levels stable. What I'm not understanding is that I thought ph rises during lights on (photosynthesis) and lowers when lights out. So at some point tonight the co2 should stop, correct?
