city water is 70 - 90ppm pH 7.8 - 9
I like the idea of not needing so much pH down but I read two disturbing things:
RO water is bad for a pH probe so how do I measure ppm (one probe for both)?
also read to add back tap water (can't find it now)
***? my water is 70, I reduce to 0 and add back in 50 of the **** I just filtered out? I'm buying RO to get rid of 20ppm?
