Ok here's my numbers...

Went to the local pool store:

TDS 4500
CYA 20
Total CL 3.4
Free CL 3.1
PH 8.2
TA 111
Adjusted TA (?) 105
Minerals 2900

26,000 IG vinyl pool....Saltwater (400 lbs just added this morning) Just put in around 3-4 lbs of stabilizer. Poured 1/2 gallon muratic acid (all I had) I also have PH - which I may add.

What should be my next step?

I also have forgotton how much muratic acid to put in to lower PH by x amount.

Thanks to all..

Next step is to circulate for 4 hours, and retest. Post your numbers back here. I'm thinking your pH is still going to be high, so you may have to add that pH-. Right now though, it's a "wait and see" game.
