Aquarium filter water return chamber

Image Number 3 for United States Patent #7601258.

An improved water return system for water reservoirs such as aquariums and ponds that provides a return of filtered water through a series of holes rather than a curved weir or spillway. The use of the holes provides for high oxygenation of the water prior to its return to the water reservoir to the benefit of life in the water reservoir. Further, the use of the holes provides reduced noise upon the return of the water because of the surface tensions attracting adjacent streams to each other. Also, placement of the holes provides a damming effect for the filter media that can become a site for the cultivation of beneficial bacteria that are necessary to remove ammonia and nitrites from the water by positioning the media mostly out of water, thereby allowing necessary oxygen to be freely available to grow bacteria.
