I was measuring ph levels of my RO top off water it was around 5 and I'm trying to keep my system at 8.0 - 8.3. So I was wondering if it is pho-pa to buffer a gallon of top off water? Just a thought... does the top off even impact the PH that much or is the disolved salt in the system enough to counteract any PH swings when toping off..
