Dimensions: 20.5" x 12.6" x 27.3" (L x W x H)

Complete with collection cup, built-in gate valve to fine tune the skimmer's performance, air silencer, removable base and three submersible ATI-Sicce pumps. In-sump installation only. "Thread-Wheel" design and super efficient ATI-Sicce pumps produce an extremely dense water/air mixture that outperforms much larger skimmers while consuming less electricity and transferring less heat to the aquarium. For every 3 parts of water each pump pulls in 2 parts air for an efficiency rating of approximately 67%. Most other skimmers on the market have an efficiency of less than 35%. Power Consumption: less than 100 Watts (Approximately 30 Watts per pump). Warranty: 1 year. Recommended Tank Size: 300-750 gallons.
