Maintaining Co2 levels question

Hello guys,

Previously was using a paintball setup and a low bps that ran 24/7, it never really hit totally lime green on the drop checker because it was to difficult to adjust the bps during photo/non photoperiod. I now have purchased dual stage regulator/solenoid setup, and I'm wondering what is the best way to start experimenting with dialing it in. I have a 27gallon Cube, 18" tall, 16 watts of LED, and 36watts of PC, I'm not sure what lighting range this places me at? I run the lights at night so as not to increase temperature during heat of summer, I plan on starting my photo period at 5pm, so should I have a timer on the solenoid to come on before the lights, when does should it turn off, if so, how long? One thing I'm hung up on is saturation of the C02 across the period, it seems to take a long time to get the drop checker green again after C02 was off, so I feel like half the photo period is wasted trying to get it back up. Any tips are appreciated to get me started with experimenting effectively and not wasting a whole lot of time.

Depends on your diffusing equipment and if you have only plants or not. I would start at 1 BPS. It will probably take a week to see if you are making progress, but a little CO2 is better than none.
If you have a solenoid on your reg, I would plug that into a timer and have it come on 1 hour before your lights do.
