Co2 setups with ph controller

[axl]

I just setup my pres co2 kit with a ph controller and want to no do people use a timer on there solenoid???. I dont think i need 1 if i have got a ph controller is that right. Do people run a airstone on a timer for the night even if we have got a ph controller. Cheers Axl

no need for a timer on the co2 the ph controler will moderate the dosage, I NEED an airstone at night or else my fish look VERY unhappy come morning.
