Soda ash raises pH and TA. Borax raise pH without affecting TA much which is why we prefer it to soda ash.

Cool. I guess all the reading up I'm doing is finally sinking in (no pun intended).

btw, what does the "PF=6" that was added to my signature mean?

PF stands for "Pool Factor" which is a calculation that Pooldoc uses to estimate effects on water with given amounts of chemicals. Here is something I copied and pasted from another post Ben wrote that may help you better understand how it works:

PF = pool factor.

If you add 1 lb of chlorine gas to a pool with a PF of 1 (120,000 gallons = 1,000,000 lbs) you get 1 ppm of chlorine.

If you add 1 lb of chlorine gas (100% chlorine) to a pool with a PF of 10, you get 10 ppm of chlorine.

If you add 1 lb of dichlor (55% chlorine) to a pool with a PF of 10, you get a 5.5 ppm of chlorine (1 x 10 x 0.55)

Thanks for the explanation. Gee, and I thought I just had cool factor

You do, Big Splash, you do!
