Add chlorine. That is all that is needed.
Read ABCs of Pool Water Chemistry. You need to understand what the pool needs and why. The app just gives suggestions for you to consider.

Thanks! I just added two cups. I have read the abc but I’m completely new so I’m still trying to figure it out.

The pH is what matters. TA being high only is a problem if it makes the CSI super-positive. Otherwise, higher TA will make the pH rise faster naturally. Add acid when your pH gets to 8.0 to bring it down to 7.6 (you need to know the TA when adding acid for PoolMath to give the correct recommended dose), and then the TA drops a little. pH naturally rises, acid added, pH and TA drops, and you repeat. Over time, the TA will lower and the pH rise will slow down a bit until you get down to TA in the 50-70 range and acid addition becomes rare.
