    Adding Bleach to my water - Need a good calculation

    I am switching to straight bleach as a sanitizer. I am looking for a good way to calculate the amount I need each time I check the FC. I know I need to increase my FC to between 7-10 PPM based on my CYA at 80. Any help here would be great. Here are my current numbers:

    11,000 Gallon Fiberglass IG pool
    Sand filter
    FC 3.0
    CC 0.0
    PH 7.6
    TA 80
    CH 200
    CYA 80

    "PoolMath" button just to the right of "Forum" will do the work for you!

    Pool School - PoolMath explains how to use the link they all posted.
    16K freeform gunite with spa; Pentair 4000 DE filter; Century Whisperflow 1 HP; Pentair Minimax heater.
    Troublefree does not mean Maintenancefree. It's like brushing your teeth: You can spend a couple minutes a day and pennies a week or go to the dentist once a year and spend several thousand dollars.
    A pool is like a pet - you have to feed it every day, even the days you don't want to play with it!
