ABSTRACT:
A water pump assembly for an aquarium aeration system includes a housing surrounding an electric pump. Within the housing, a water conduit passes an impeller of the pump for the generation of a stream of moving water. An air-breather conduit conducts air from a location above the housing to an air-induction port in a sidewall of the water conduit. The aquarium power head is provided with a clamp for attaching the power head to the aquarium tank. The clamp has a ring which mates a tubular inlet portion of the housing and engages that inlet portion. A flow diverter to adjust the water flow exiting the power head in a desired direction is adjustably connected to the outlet portion of the housing of the power head.
