Device for treating aquarium water

Abstract

Abstract A device for inserting in an aquarium for the treatment of the water in the aquarium including filtration of the water, circulation of the water and aeration of the water as well as the selective supply of treatment materials to the water. A plurality of individual screen elements are arranged in vertical alignment and progressively decrease in mesh size in the upper direction and a fluid jet is directed upwardly toward the bottom of the lowermost screen element. The fluid jet, which may be air, flows upwardly through the screen elements and induces flow of aquarium water upwardly through the screen element whereby particulate material in the aquarium water will be filtered out and deposit on the bottoms of the screen elements. The water in the aquarium has free access to the underside of all of the screen elements and particles in the aquarium water, if small enough to pass through a lower, larger mesh screen element will be filtered out from the water in an upper, finer mesh screen element. The device according to the present invention is preferably in the form of a single unit which can be placed in submerged location in an aquarium, preferably centrally of a longer wall thereof and effects continuous cleaning and circulation of the aquarium water. The individual screen elements are advantageously contained within individual housing members and a screened cap is provided for one of the housing members so that it can be mounted on one end thereof and charcoal or a treatment medium, such as a soluble chemical material, can be placed between the screened cap and the screen element in the respective housing and thereby effect treatment of the aquarium water as flow thereof is induced through the respective screen element.
