Hagen Fluval External Pump Filter 40 Gallon Tank Aquarium Model 204

New unit bought a while back but never used.  Box shows some storage wear but all parts are new and unused. The Fluval MSF (Multi-Stage Filter) combines innovation and convenience with a high level of performance. Multiple internal filtration modules allow the use of a variety of different filter media to provide optimal water quality. Always one step ahead of the competition the following up-dates have been incorporated: •  New More Powerful Motors: Superior flow rates and stronger pumping through improved head height capacity with increases of 15 to 25%. These motors will deliver higher flow rates over a longer period of time. •  New Aqua Stop: Barrel valves have been incorporated to eliminate maintenance of the Aqua Stop. The new second lever allows for flow adjustment, permitting the use of larger models on smaller aquariums or convenient flow reduction during feeding. •  Self Priming System: A check ball is used in the newly re-designed larger strainer for quicker filter priming. •  Co-Molded Impeller Cover: A silicon rubber insulation is used to dampen vibration and prolong impeller life and performance. Performance Features: •  Modular Design: Easy and Quick Maintenance •  Multiple Filter Media Baskets with Partitions: Alows the use of most filter media •  Twin Mechanical Foam Filter Screens: Efficiently trap waste and debris for cleaner water and better performance from all filter media •  Aqua Stop: Quick and convenient connection/disconnection of filter hosing •  Ribbed Opaque Hosing: Bends and turns easily without kinking, making installaton and removal easier while supporting better water flow •  Self Priming: Quick and easy to start •  Pump Output: 180 U.S. gal/hr, 680 L/hr •  Aquarium Size: 40 gal/ 200 L
