high cya, high chlorine, is liner safe ?

[aylad]

Your liner should be okay as long as your shock level drops along with your CYA level--once your CYA level gets below 90 I would let the shock level drop to 20, etc.

If your CYA adjustment is to be done by Wed or Thursday, I think I'd just let the Cl drift down, get your CYA to where you want it, and then shock--you would use less chlorine that way.

thanks janet.
just to be sure i understand, when you wrote
>>I think I'd just let the Cl drift down,
you mean down below the shock point - assuming i
really am done with my CYA lowering by thursday.

followup question:
does this mean it is safe for the liner to keep chlorine
as per ben's chart for high CYA ?
so if i just get to the 60-90 CYA range
i could keep my chlorine at 10ppm
and my liner is OK ?

thanks
