Had pool opened last week, and didn't get tf-100 in until today. I have been running the pump a lot, initially too cold for swg, Then when temp came up, salt level was too low. The salt level was only 1800, so added salt to get up to 3100ppm and now swg running. I got kit in today, here are results.
Ph 7.8
FC 4
CYA 30
TA 140
CH 325
I plugged everything into pool math. I need to add some cya, but wasn't sure what to do about TA. It says to fix the TA i should lower the ph to 7.2 with acid, then aerate to raise the ph back up. I figure I should add some cya first, then repaet test in a week or so. At that time I can adjust the pH/TA. Is that ok, or should I proceed differently?

Adjust CYA to help protect your FC level and you can always adjust TA as needed per the
