Dichlor adds CYA

[ShadowSid]

From Pool Math:
Note: Dichlor and trichlor add CYA and lower pH.
How much CYA? I have dichlor bags to use up (when my CYA gets low , not now); 99%, available Cl 55%

Second question
Can you suggest a pump RunTime ( # of hr per day) based on the info in my signature, I know it varies by temperature & other factors & I will tweek it, but about how many hours will it take to get 1 turnover?
Thank you.

In your pool, one pound of dichlor will add 2.2 ppm FC, and 2.0 ppm CYA.

Turnover is a myth.
Your run the pump for a reason. First is to create/distribute the chlorine that is added every day. Second is to skim the surface.
Start with running the pump 6-8 hours per day. Be sure to add your liquid chlorine at least 1 hour before the pump turns off each day. If you need more skimming or the pool is not as clear as you like from debris, run the pump longer.
