TA at 120, pH at 7.5

[GreatCanadian]

My neighbor's pool has a TA of 120, and a pH that appears be locked in at 7.5. Is there any need to lower the TA? She wants to, but I told her there's not need to if her pH stays where it appears to be staying. If pH rises, the TA will drop when I lower the pH anyway. Vinyl pool, SWG, CYA 70. Thanks.

You are correct, the TA doesn't need to be adjusted to meet an arbitrary number. With a SWG, if the pH isn't drifting, then she's golden where it is.

Perfect, thanks for the reply!
