Abstract
A chlorine dispenser for spas includes a tubular container disposed within a sleeve having one closed end. The container and sleeve form a chamber for receiving the solid chlorine source. The sleeve contains apertures for providing access by water to the solid chlorine source. The sleeve is axially movable along the container, and a locknut engages the container to secure a given position of the sleeve. The container is attached to a foam-filled float, which ensures positive buoyancy of the dispenser in water. The sleeve is ballasted to ensure that the dispenser is vertically disposed in the water.
