Been there done that. The trick, for me, was to dust off my cover glasses
and put a lid on it so to speak.
The cover glasses seems to keep all the O2 from plants *and* the CO2 
in the tank.
I also turn on the CO2 a couple of hours before the lights come on which
seems to get the rich pearling going really fast when the lights come on.
Yes. pH-swings, but as Mr. Barr says:

that's what happens in natural waters.
