Here's an update for my situation. I shocked at 20 ppm, as recommended, for 3 days. The pool cleared a bit more. The aeration method seems to have worked a bit too. The ph did rise but alk rose very little, if at all. I kept adjusting with muriatic acid, as recommended. I put in a little clarifier, once my levels were back to normal, and presto, after a day, the water was crystal. Has been since. Here are my present numbers from this afternoon:

PH 7.2
TA 130
CH 300
FC 12
TC 12
CYA 45

Thanks again for the replies and help!
