ABSTRACT:
Retrofit apparatus for retrofitting an ozone generator to a spa, hot tub, recreational fountain, or similar facility, and a method for treating biofilms therein, are disclosed. Fittings inserted into water and air circulating lines associated with such water holding facilities, and covers provided over inlets, generally inject, retain, and concentrate ozonated gas in such lines, especially while they are not filled with water. In some embodiments, an ozone-providing plug is provided to at least one water outlet of a spa or hot tub, with other outlets being blocked. In some embodiments, covers for suction inlets, and plugs for water jets, have features to provide ozone to water circulation lines when not filled with water as well as when the tub is filled and water is circulating. In some embodiments, plugs for water jets are ejected and subsequently provide ozone to water circulating in a tub.
