The readings show 0 Chlorine, even after shocking adding 1 lb of Super Sock It, PH is 8.2 after I added about 15 oz. of PH + ( to much), AlKalinity of 450 ppm, and Hardness of 450ppm.
If I go by the HTH web site I'm supposed to add 1lb of PH - to get the ph down, but then 633 lbs of PH- to get the TA under control.
What the *#!! do they think I'm smokin'
If Super Sockit is the 62% Cal-hypo, it will push your pH up. It's also pushing up your hardness. STOP USING IT!

We always say use bleach or liquid chlorine. If your CYA is low (like, 0 or below 20) you can use Tri-Chlor tabs because they will lower pH and add CYA.

You can use pH-, or generic Dry Acid to lower your pH. But adding a cup of muriatic acid instead may do far better.

Read up on lowering T/A. You're not going to use 633#!

But you will need to repeat the aeration process many times. Use acid to lower pH to 7.0, then aerate to raise it back to 7.3 or more. Then add acid again to lower, and aerate again. Each time T/A will come down--450 almost guarantees a cloudy pool, especially with high calcium hardness. It's going to take a few gallons of muriatic acid to do it.
