Reef Octopus Hang-On Back Classic skimmers are a proverbial favourite. With its unique design, the pump is mounted externally and under the actual skimmer body (90-HOB,1000-HOB and 2000-HOB)allowing for much less room needed behind the aquarium and less heat-to-water exchange.
The OCTO Classic series HOB is constructed of high-quality acrylic and equipped with the new highly efficient Aquatrance pinwheel pump that produces an ideal mix of water and air for optimal waste removal.
