Best way to lower TA with a SWG pool?

Hi folks:

First year pool owner with 32K gallon, gunite pool with SWG.

All chemistry values are in line with the suggested levels on this site for a plaster pool with SWG....EXCEPT for my TA.

TA should be 60-80 and in reality I'm about 140-150.

I know you can lower TA with muriatic acid. My question is, do I need to aerate to increase PH so I add more Muriatic Acid?

Or will the normal PH rise that I get with my SWG do enough to raise PH?

Before you try changing the TA, be sure you have a reason. If pH is difficult to maintain at a low enough level, it might be worth lowering your TA. If pH control isn't a problem, don't worry about TA.
