    It depends on the size of your pool. As Leebo suggested, the Pool Calculator is a wonderful way to figure out the answer to that kind of question.

    Welcome to the forum

    If you aren't able to access the, you can use the ole pen and paper to help you figure doses.
    Here's a snippet from pool-school/swimming_pool_definitions_abbreviations found in Pool School:

    See sodium hypochlorite, below, because that is what bleach is. It comes in 6% strength as Ultra bleach, 5.25% strength as regular bleach, and sometimes as 3% strength for some of the 'cheapie' bargain bleaches. You want to use plain, unscented bleach for your pool, not the scented or thickened kinds! One gallon will raise 10,000 gallons of water approximately the percentage of the bleach in FC (i.e, one gallon of 6% ultra bleach will raise 10,000 gallons approx. 6 ppm FC).
    For example, if you have a 20K gallon pool, 1 gallon of 6% bleach will add approx. 3 ppm FC.

    You're done SLAMing when:
    1)You lose 1ppm or less FC overnight, & 2)You have .5ppm CC's or less, & 3)your water is clear.
