Hi Psciotti;

Glad it's looking better, but don't relax yet.

+ Continue letting your chlorine drop, but not below 1.0 at any time.
+ 4oz 2x a week is OK, as long as there's no sigh of algae.
+ See what the pH is tomorrow; try to get it below 8.0 -- I'm afraid of any remaining copper coming out and staining things.

Once your pH is normal, and your copper seems to be gone, we'll have to work out how you're going to run with high CYA. There are two choices. You can run high chlorine, which requires a DPD-FAS testkit (sorry, maybe you've gotten one -- I forget) OR you can run 5 - 10 ppm chlorine PLUS small doses of sodium bromide to create a free bromine residual.
