Last year when I first filled my pool, I brought my TA down from 240 to 80 ppm so I could add 50 ppm borates to help stabilize my TA and pH for the entire season. This 80 ppm TA level was recommended by someone as being a good level to start with when adding borates, so I followed that person's advice. I still had to add acid every few days to keep my pH at 7.5, so the borates did not stabilize my pH at 7.5 as I thought they might. But my TA did not change all summer after the borates were added.
Yesterday I learned about Ben Powell's "high pH pool" theory and it made me wonder if I wasted my time/money last year adding acid every few days just to keep my pH at 7.5 all season? Perhaps if I had just let my pH go rather than constantly adjusting it, it might have stabilized on its own in the 7.8 - 8.0 range, which according to Ben would have been just fine!?
I recently filled my pool again with the same source of TA 240 ppm water as last year. But this time I wonder if I should just "leave my TA alone" and add the 50 ppm borates as soon as I get my pH into the correct range? If I add borates at such a high TA will they keep my TA stable at 240 this year?
And how will this affect my pH levels? Will my pH keep climbing all season in an attempt to reach equilibrium with my high TA? Or will the borates be able to buffer my pH enough to keep it more stable than last year, and possibly reduce my need to add acid frequently?
