ABSTRACT:
Describes apparatus for dispensing a sanitizing chemical into a swimming pool. The apparatus is a container having a closed bottom, a lid with a dispensing opening, and a plate with colored markings that is larger than the dispensing opening and freely moveable vertically resting on the bottom of the container. The plate has a specific gravity of less than 1.0. In operation, the container is filled with solid sanitizing chemical, e.g., calcium hypochlorite, and placed in a skimmer basket associated with the pool. When the sanitizing chemical is completely dissolved by water pumped through the skimmer basket and recycled to the pool, the plate floats to the top of the container where it can be observed readily to indicate that the apparatus needs to be refilled with sanitizing chemical.
