ABSTRACT:
A pool chemical dispenser is provided that comprises a rotatably adjustable top, a container and a ballast disk cooperative with the top such that the specific gravity of the material of the top and the container is less than 1.0 and the specific gravity of the material of the ballast disk is greater than 1.0 thereby permitting the dispenser to float off the bottom of the skimmer in which it is immersed in water when less than about 10% of the pool chemical remains in the container and invert, remaining on the top of the surface of the water to indicate the pool chemical is exhausted.
