I have a Royal Exclusiv Vertex Alpha 170 protein skimmer. This comes with the Red Dragon pump. This skimmer works great and is dead silent. These were really expensive skimmers new. The output pipe on this is glued on. The pump itself is worth more than I'm asking!! Tank Size: 140 - 220 Gallons (550 - 850 L) Footprint: 9.5" x 15" Height: 23" Air Draw: Adjustable 1000 to 1400 LPH $250 shipped firm as shipping will cost over $50. I would do $200 local pick up
