- PF is the ratio between your pool and a pool with 1,000,000 lbs of water (~120,000 gallons). The calculation of the dose effect on a pool is:
PF x %Concentration x Pounds- Yes. 1 gallon of 10% bleach is ~ 0.8 lbs of 100% chlorine equivalent, and will add 7.7 ppm of chlorine to a pool with a PF of 9.6.
For example, with 2 lbs of dichlor, the calc would be9.6 x 55% x 2 = 10.5 ppm FC
. . . and . . .
9.6 x 50% x 2 = 9.6 ppm CYA
