Ultraviolet sterilizer
First Claim
1. An aquarium comprising a recirculating water flow filter system including an air stone for mixing air with the recirculating water, a diffuser connected in said recirculating water flow system, said diffuser comprising a container, baffle and conduit means for carrying the air-water mixture from said recirculating water flow system to said container and thereby thinning the flow sheet of said air-water mixture passing from said conduit means to said container, an ultraviolet sterilizer comprising a source of ultraviolet light, a housing for holding said source of ultraviolet light and means for attaching said housing to said diffuser and locating said source of ultraviolet light proximate to said sheet of air-water mixture flowing out of said conduit means for irradiating said thinned out air-water mixture.

Abstract
An ultraviolet sterilizer for a recirculating water flow filter system in which the sterilizer includes a low power source of ultraviolet light. Means are employed to thin out an air-water recirculating sheet and the ultraviolet sterilizer is placed a small distance from the sheet in order to irradiate the mixture and create an ozone layer further sterilizing the recirculating mixture.

6. In an aquarium ultraviolet sterilizer comprising an ultraviolet light for use with an air driven recirculating filter system, said sterilizer comprising conduit means for carrying the air-water mixture being recirculated, thinning means placed in the path of flow of said air-water mixture for thinning said mixture, and housing means for locating said ultraviolet light proximate to said thinning means for irradiating said air-water mixture and for generating ozone to oxidize said mixture.
