ABSTRACT:
An aquarium device for use in an aquarium tank, the device includes two cylindrical airstones each having a nozzle with an end portion thereof secured within a bore of the airstone and an opposing stem portion thereof extending from the airstone. A T-shaped connector includes a tubular central portion for receiving the stem portions on the nozzles of the two airstones. A connecting stem portion extends from the central portion of the connector for coupling to an air hose. The stem portions on the nozzles of the airstones and the connecting stem portion on the connector are substantially identical in shape, whereby the airstones can be used as a pair in conjunction with the connector, or individually by directly connecting the airstone to the air hose.
