best way to maintain PH with a reactor??

[Bryan]

Having the same problems. Going to put mine on a controller so it shuts off at 7.80. I have heard of some users overdriving the CA reactor a bit during the day and shutting the Co2 off at night. Supposedly works well

I was thinking of just adding some PH buff ones in a while.
Just wondering what other people with reactors are doing??
