Tests taken over a week:
FC 0 5 5
TC 1 5 5
CC 1 0 0
pH 8 7.4 7.2
TA 130 100 80
CH 120 120 120
CYA 0 40 40
salt 2320 3800 3800
Since the first test I've shocked the pool with trichlor, added CYA and salt, aerated, added muriatic acid, and aerated some more.
I just added 5lbs more CYA today after the posted test, which pool calculator estimates will bring up CYA by 22ppm so I need to buy some more CYA tomorrow to get to the target 70-80ppm ($80 worth of CYA - seriously hoping CYA remains stable for the rest of the year!). The 5lbs CYA dissolved today maybe have dropped TA even further and most likely lowered pH.
So now do I need to aerate to get the pH up or let it drift up over time? The water temps range from mid 60s to 70s depending on ambient temperature so it will still be a few weeks before we're in the pool.
I've kept the solar cover off while aerating, so I'd like to stop aerating and add the solar cover if the pH will stabilize on it's own (via SWG) without aeration.
