    In your pool, each quart of 8.25% bleach will add about 1.6ppm of chlorine.

    Question Re: bleach calc

    I am having the same problem with the link. I keep getting "unexpected error" from both IE and Firefox. Would running Windows 8 have anything to do with it? Frustrating. I need to bring my FC level of 3 up to my CYA level of 63. I don't know how much 8.25% of bleach to add. Also my CC is .5 If I add the amount of bleach I'm supposed to tonight, at what point can I add Borax to raise my pH level?

    In a 13,600 gallon pool, each quart of 8.25% bleach will add 1.5ppm of chlorine.

    You can add the Borax and the bleach one right after the other with no problem. I do it all the time.

    Hope this helps.

    Like this:

    1. Find your pool factor: Divide 120,000 by the gallons in your pool and round: 120,000/13,000 ~= 9.23 ==> So . . . your PF = 9

    2. Use the following values: 3% bleach @ 8.4 lbs/gal; 6% bleach 8.6 lbs/gal; 8.25% bleach 8.8 lbs/gal

    3. Calculate chlorine ppm per gallon for YOUR pool: => FC ppm = PF x lbs bleach x % => 9 x 8.8 x 0.0825 = 6.5 ppm.

    So, you get about 6.5 ppm per gallon of 8.25% or 1.5 ppm per quart.

    Thumbs up Re: bleach calc

    Ah! Thank you for showing me how to come up with the numbers. Watermom gave me my calculation but it's nice to know how she got it, too! I don't know why some of us can't use the link, but thank you for taking the time to write that out. You guys are great!!

    I've got a friend's Win8 laptop here -- so I can remove and replace Win8 with Win7Pro -- I think I'll try and see if I have problems downloading using Win8.
