I am planning on shocking my pool today. It has been unused and uncovered for at least four years. I have all of the debris out of it. It actually doesn't look that bad right now compared to a week ago. Anyway, I added cya and got the level up. Now I want to start adding chlorine and would like to have someone double check my math. Can anyone take a look and let me know if I'm correct?
I think my target shock level is 20? So with 12.5% bleach I need to add 239 oz. Thank you for the help in advance.
