Dear Orion,
I really liked your article on pH it's very informative. There was just one thing I picked up and that was the definition of pH itself. While it is a measure of degree of acidity or alkalinity it is actually a measure of percentage of Hydrogen in your water as in [p]=percentage and [H]=Hydrogen. The more Hydrogen you have the more acidic and likewise the less acid you have the more alkaline your reading will be. That's why you'll put in more minerals,trace elements and salts or what have you to make it more alkaline; The more hardness there is the less likely it is for the pH to end up acidic because you have less Hydrogen overall. Just a thought from my old grade 12 teacher in Chemistry...Loved your article...
