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 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.
