ACID lowers PH - lower PH also affects the TA and lowers it until the PH comes back up and then the TA comes back up. Just lower the PH to 7.0-7.2 and then aerate by having a pool party (splashing) or by turning a return up to disturb the water surface. When you aerate at a low PH, then the PH rises but the TA stays lower - you do this a few times (over a week or two) and you will be set.

DO NOT add 6 gallons of acid to your pool.
