What is the best time to start the CO2 system as far as time goes? Do you start the system before the lights turn on or at the same time? If it's best to start before the lights turn on how soon 15 mins or 1 hour?

It depends on YOUR setup and how efficiently/quickly you can get to excellent c02 levels when the lights are on...

Some folks pick 15-90 minutes. Some need less based on tank size and/or diffusion method..

More details on your tank will provide a better response unless the above general answer is sufficient to your query.

I agree with Gerryd. Personally, I set my CO2 to start 30 minutes before my lights turn on. The CO2 then turns off 30 minutes before the lights turn off.
