Abstract: A floating pool chlorinator made of a chemical resistant material comprising a float assembly and basket assembly. Solid pool chemicals are dispersed at a selectively micro-variable rate by engaging the float assembly more or less into the basket assembly thereby exposing to a lesser or greater degree one or more vent holes in the side of the basket assembly. The float assembly is preferably hollow and permanently sealed and dimensioned to float the combined weight of the device and any chemicals placed inside the basket assembly. A child proof lock ring is provided to prevent unwanted exposure to caustic pool chemicals. Optionally, a drain and tether are individually present. The floating pool chlorinator floats in a pool and disperses selected solid pool chemicals dissolved in a pool or spa.
