I have the same problem here in Lansing MI. After doing a bunch of tests and
dragging my wife downstairs into the fish room (she is the chemist in the
family), I have determined that my water is filled with CO2. My water from
my Culligan RO unit goes from 7 to 8.4 after aerating it for just a few
minutes. I have tested the water at numerous stages of RO membrane use to
make sure that I did not have anything in my water to raise the pH and have
found nothing in my water to effect the pH except the CO2.
