Can someone please help me make sense of these numbers? My tap water comes in at a PH of 7.8 while my RODI water is 6.0. Is this typical? Test kit is a brand new API master set.

koop, you need to let the water set for a while, an hour or two before you do a pH on it. the RO should come darn near 7.0 But is does come out a little acidic at first, but usually ends up near neutral.
