How much bleach equals one pound of shock?

The equivalence between bleach and shock (chlorine) can vary based on the concentration of the bleach. Generally, household bleach contains about 5-6% sodium hypochlorite, while pool shock typically contains 65-75% calcium hypochlorite. To convert, approximately 1 pound of shock is equivalent to about 2.5 to 3 gallons of household bleach, but it's important to check the specific concentrations of the products being used for accurate measurements.
