ABSTRACT:
A portable apparatus for the filtration and/or chemical treatment of make-up water for a pool or spa. The apparatus connects to the end of a make-up water fill hose using a non-metallic threaded connector. The apparatus also includes a hollow core for holding pool chemicals or diatomaceous earth, an inner filtration media surrounding the hollow core, and an outer filtration media enclosing the threaded connector, hollow core and inner filtration media. The lower end of the outer filtration media extends past the connection of the hose to the threaded connector to form a skirt, which prevents the connection from contacting the interior of the pool or spa. Additionally, buoyancy is provided such that the apparatus does not contact the bottom of the pool or spa.
