    % of Chlorine in Bleach???

    So some plain bleach I picked up at Smart and Final says 8.25% Sodium Hypochlorite yet yields 7.66 % available Chlorine.
    Which number do I use in the "Pool Calculator" ??

    Swim-Ex 400 paddlewheel swim spa - 3000 gallon -Pentair CCP-320 - Coates 11KW heater - 1/2 hp pump - Outside in pit

    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.
