ABSTRACT:
An aquarium filter and aerating device for insertion in an aquarium tank comprising an elongated hollow body member having an open bottom end and defining an interior chamber therein. An upper end wall on said body member closes the top of the chamber, and includes therein a plurality of apertures. An air conduit connector extends upwardly from the upper end wall through which air can be pumped from an external pump into the interior chamber. The air lowers the water head in the chamber to an appropriate level within the chamber, and forces the air pumped into the chamber upward and out through the apertures to cause a stream of air bubbles to flow into the aquarium tank to thereby aerate it.
