I've been in the forum for some time, and I've read pool school thoroughly. However, I remain confused on the difference between raising pH and raising TA. My memory from chemistry is that water is either basic (alkaline) or acidity, and the number that tells you that is the pH. So is making the water more alkaline (aka raising TA) not the same as raising pH? Or am I mistaken? In pool school both of those topics have separate and distinct paragraphs, therefore I assume they must be unrelated.
