Air stone / agitation ...

just set your co2 to turn off an hour before lights go off and turn on hour before they go on.. But its pointless to run airstone at night. You will experience great ph fluctuations like that.
I have Co2 set to go off 1hr before lights are off and come on 2hrs before lights come on in morning to make sure the water is saturated when the lights fire up.
However I have read that there are benefits to having an o2 source at night when the plants are not providing it. Found an interesting post on another forum showing DO (Dissolved o2) results at different times of the day/night...

I should add that I currently have practically zero surface agitation. The post I referenced above said the only time you will get PH fluctuations is if you have lower KH levels - mine has been pretty high.
I think I might put an airstone on a timer for a few hours over night.
Well you can add something like a co2 diffuser but plug it in for o2.. and run it on a low setting. Small bubbles will be dissolved fast and will give little to no surface agitation.
