Zoo Med Power Sweep Powerheads are designed to fit all undergravel stems from 3/4" to 1 1/8". They are self-rotating, which creates greater surface agitation to allow a high oxygen exchange rate. In addition, the rotating motion breaks down the surface film of dead bacteria which can inhibit oxygen exchange. All models feature a Venturi aerating system, adjustable flow rates and all mounting accessories. Can be used in fresh or saltwater. Great for use as a wave maker in marine tanks. CSA Approved.
