Holy Crap!! You were not joking. Before going further do this test for me.

Take some of your regular tap water (like a gallon) set it to a certain ph (lets say 5.6) Then leave it overnite and check the ph in the morning and let me know what it is....Don't buy anything until you've tried this. Let's start there.
