    bleach calculator link "not found"

    trying to figure out how many gallons of bleach to put in a 19237 gal pool.
    saw the link, also read some instructions re the % = ppm, good to know with my cya @ 90 the chart calls for FC 35. I am at 25.5 now so would I add 9.5 gallons more of bleach. Also is bleach upping the cya? Was 60 yesterday.
    Thanks for any confirmation and stuff re the cya going up.

    You want Pool Math, the link is one of the tabs at the top of the web page.

    What % is your bleach? That goes in the % weight of bleach cell of Pool Math. Even if you're using 8.25%, it should only take 2.75 gallons to raise your FC by 10 ppm.

    CYA will not go up with bleach. Only with powdered Dichlor shock or usage of Trichlor tablets in your Hayward chlorinator.
