The Powersweep 228 Powerhead is a unique aquarium powerhead that actually sweeps side-to-side to eliminate any dead spots within your aquarium to create greater surface agitation allowing a higher oxygen exchange rate. Can be used with your undergravel filter or placed anywhere in your aquarium to produce extra water movement. Includes venturi air inlet as well as dual suction cup mount. Fits all undergravel stems from 3/4" to 1 1/8" diameter. Pumps 270 gallons per hour.
