<p>A device for dispensing chemical agents into a body of water includes a plastic, bucket-like container (14) having the chemical agents (16) disposed therein. The side walls (24) of the container are perforated with a plurality of perforations (44). Wrapped around the outside walls of the container is a removable cover layer (18) disposed over the perforations. Disposed within the container is a layer of closed cell foam (48) to provide the container with sufficient buoyancy to float at the surface of a body of water. The device is especially useful in the fertilization of algae growth within a lake or pond.</p> |
