Once your TA gets down to around 80 or so, go back to normal pool maintenance. Your pH should climb up on it's own, and you'll add MA to drop it, and over time your TA and pH should reach a nice balance where you don't have to add MA much at all. Some pools are annoying and have trouble finding that balance, some fall into that balance quickly. I find for my pool 50ppm TA is perfect, and my pH rises at most 0.1 per week, so I add acid once a month or less.
