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

I just leave mine. My PH goes 7.8 at night and 8.1 during the day. I have my controller set that if the tank Ph goes below 7.75 that the calcium reactor's CO2 feed would just shut off. I've thought about running my air intake for the skimmer to feed from outside, this would raise the PH with fresh air going in. I might still do that someday when it's warm out.
