Abstract: An aquarium filter with water stream diversion system and method of use thereof, having an intake, an outlet, and a pump to draw water into the intake and discharge water from the outlet. The system further includes a water stream diversion conduit having a first open end, an opposite second open end, and a fluid channel between the first and second open ends. The first open end of the conduit can releasably connect to the intake of the pump or the outlet of the pump. When the conduit is connected to the outlet of the pump, the water is diverted from the outlet of the pump into the conduit, for discharge from the conduit. When the conduit is connected to the intake of the pump, water is drawn into the conduit and discharged from the conduit into the intake of the pump.

Abstract: A combination water and air pump and method of use, for simultaneously circulating and aerating water. The pump including a housing, a first chamber for circulating water, having an inlet for water to be drawn into the first chamber and an outlet for water to exit the first chamber, a second chamber for aerating water, having an inlet for water to be drawn into the second chamber, an apparatus to draw air into the second chamber, and an outlet for aerated water to exit the second chamber. A rotatable shaft connected to a first rotatable impeller in the first chamber and a second rotatable impeller in the second chamber. In use, rotation of the shaft simultaneously rotates the impellers to circulate water within said first and second chambers.
