CO2 timer ?

I've read in a few different places that pressurized CO2 on a timer should come on 1-2 hours before the lighting. I have 3 stages of lighting running 4 schedules-

Event #1- White Lunar lights from 6:00 AM-10:00 AM
Event #2- (1) 25W T8 from 10:00 AM-08:00 PM (Dawn, Dusk & Full Day)
Event #3- (2) 96W CF from 2:00 PM-7:00 PM (Full Day)
Event #4- Lunar lights from 8:00 PM-11:00 PM (for night viewing)

The CO2 comes on with the 96W CF's. What do you think? Should I reprogram the timers, shortening the T8 up 2 hours to 12:00 AM-8:00 PM and have the CO2 come on with the T8 @ 12:00 AM instead of at 2:00 PM with the CF's? Or should I add another timer to start/stop the CO2 & run it from 10:00 AM-7:00 PM?

:eek5:

Obviously I'll have to readjust the bubble count to maintain the same level of CO2 over the new run period as I had with it only running 5 hours.
