Abstract: An improved and more efficient design for an air driven algae filtration system is achieved because there are no moving parts other than an air pump, and the air is used twice. After using air to circulate water through a filtration unit, the air, still under pressure, is separated from the water. The air is then plumbed to other apparatuses or used for cooling. This allows the filter to be utilized using less electricity. The water is de-gassed before reaching the algae filter. Therefore, no splash guard is necessary to prevent water from splashing the lights. With no splash guard, lower wattage lights can be used to illuminate the algae. This also increases the efficiency of this system. This filter also lends itself to maintaining a reef aquarium.

Abstract: 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.
