Abstract: A swimming pool skimmer and chlorinator apparatus for use with a conventional pool skimmer system. The swimming pool skimmer and chlorinator apparatus preferably includes an axially bi-sectioned basket member which preferably collects skimmed debris in an upper axial portion and preferably retains water purifying chemicals in a lower axial portion, to generally eliminate incidental direct human contact with the water purifying chemicals. The swimming pool skimmer and chlorinator apparatus also preferably includes a connector to connect the separate axial portions of the bi-sectioned basket member and a security mechanism to generally prevent unintentional separation of the axial portions of the bi-sectioned basket member.
