I put mine on 1 hour before lights on and 1 hour before lights off.
Having the co2 on after lights is a waste.
Some people have it switched off much earlier than 1 hour before lights off.

i have mine 2hrs before lights on, and 3hrs before lights off. Plants strat to wind down towards the end of the photperiod, and what CO2 is left in the water will be plenty. It doesnt gas off, or get used that quickly which is why i turn mine off so early.
