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%.
