The total dissolved solids will increase in the pool accordingly, and may well be assisting the TA in acting as an extra buffer to minimize pH bounce. This is just a theory on my part. Someone with better chemistry than I, hopefully may enlighten us further.

It was not so much an argument as it was curiosity on my part as to whether or not I was doing something wrong. Should I not use PH+ and PH-? What do you mean by up salt?
