Abstract
A swimming pool chemical tablet and storage container is provided for use in a skimmer of a forced circulation flow system, the swimming pool chemical tablet having a radial sidewall contact surface which contacts the frusto-conoidally shaped sidewall of the container at a location at least equal to one-half the predetermined height of the tablet to form a tablet-sidewall flow space above the sidewall contact surface to control the rate of dissolution of the tablet when water is circulated in the forced circulation flow system.
