Abstract
A capsule and a method of making a capsule for use in the dissolution of a chlorine chemical compound into a body of water. The capsule comprises a tablet section having at least one chlorine compound tablet and a shell securely fitted about the tablet section. The shell has two apertures at opposite ends, each extension extending away from the tablet section and having a conduit communicating with an aperture to reduce the dissolving rate of the chlorine into the water. The ends of the extensions may be shaped to prevent the capsule from standing on its ends.
