Lighting/CO2 photoperiod question.
Ok so I just got my pressurized CO2 system up and going, which is going to allow me to extend my photoperiod from 7 hrs. to 10 hrs. My question is: I understand that many people have their CO2 come on about 2 hrs before lights on, when is it best to turn your CO2 off? Is it better to turn the CO2 off with the lights or would it make sense to let the CO2 turn off an hour or two before lights out, therby allowing the built up CO2 to be consumed by plants and lessen chances of night gassing fish? Thanks all for your advice.
