Distilled water is pH 7, PERIOD!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! If your testing it as acid, you need to read your test kit and get one just for water, there is a HUGE differance, you can not test water with a strip, you use liquid to test water and when you do it right, it is pH 7, neutral, no minerals to throw it alkaline or acid.
This is why I pitch any and all books where the author can't even get water straight, if they know enough to figure water out, then they can be 100% backwards about human health.
