We are told we need to alkalize, but what does that really mean? Many of us think that acidic water is just water with lots of acidic minerals in it, and alkaline water is water with lots of alkaline minerals in it - calcium, magnesium, potassium etc. But you can have acidic water with both acid and alkaline minerals in it; just more acids than alkalis, so it's not quite as simple as you may have thought.
