Regarding your Numbers: PH 6,9 ,Alk 110,Cal hd 200,copper 5, CYA 120, chl .5

I'm not a forum expert but:

Your PH is too low and may be harmful to your pool. Raise it to at least 7.0 to be on the safer' side. 7.0 is also a good number to target for shocking with metals. After you get your metals under control you could maintain it at the 7.2 range.

Your CYA is going to require you to 'Shock' at about FC 25ppm. (this may be a problem with metals and Sequestering, I'm not sure at what point the Sequestering Agents breakdown)

Stabilizer . . . . . . Min. FC . . . . Max FC . . . 'Shock' FC
=> 0 ppm . . . . . . . 1 ppm . . . . . 3 ppm . . . . 10 ppm
=> 10 - 20 ppm . . . . 2 ppm . . . . . 5 ppm . . . . 12 ppm
=> 30 - 50 ppm . . . . 3 ppm . . . . . 6 ppm . . . . 15 ppm
=> 60 - 90 ppm . . . . 5 ppm . . . . . 10 ppm . . .. 20 ppm
=> 100 - 200 ppm . . . 8 ppm . . . . . 15 ppm . . .. 25 ppm

Your cl number doesn't give me enough information. This forum looks at chlorine as FC + CC = TC. FC='Good Chlorine' and CC='Bad Chlorine', TC is just how much Chlorine is at the party.

**I also took a brief look at your other Posts to see how you got to this point but coudn't find any background. So I'm not sure what your water looked like before, and what you did prior to the AA treatment.
