Based on my Ward Labs analysis, I have very soft water with a pH of 7.2. My mashes have been very acidic (4.7 range). I have been testing my tap water with ph test strips today. The strips read on a scale of 4.6. to 6.2. They show my tap water as being very acidic ( less than 4.6). As a test, I boiled a cup of my tap water for ten minutes, cooled, and then re-tested it. It registered dark purple, above 6.2 pH.
I have also tested the pH of a cup of my tap water that I let sit out overnight. Still a pH of ~4.6
How is it possible that my tap water's ph can increase two full points after boiling? Is this a sign of temporary hardness?
I have been using a faucet charcoal block filter. I havn't been pre-boiling my mash water because I thought the filter would take care of it. But it looks like the filter is not the solution for my water.
Here is my water report:

Any advise is much appreciated
