These are the test results yesterday
Yesterday I added 15 oz muriatic acid according to pool calculator. I did that for pH. That's the correct thing to do for pH, right? Since I was away from the house I just let the pool pump run for several hours. I also added a little water since the level was a little lower (it is already over 90 degrees in the afternoon where I live). The pool pump ran for 6 hours last night, and the SWG for 3 hours.
Today I tested and got
pH appears to be a little lighter than 7.5, but not yet 7.2
I am assuming the CYA is still 80 which is what it tested on 5/28. Can I make that assumption?
Did FC drop due to muriatic acid too? Am I doing okay? I imagine I should add more muriatic acid? I plan on a small pool party Friday evening, and I would like to know that my water is healthy. I have time to adjust still, so advice anyone? Thank you.
