Reef Octopus Classic 110-S Space Saver Protein Skimmer

We recommend the Reef Octopus Classic 110 skimmer for normally stocked aquariums up to 75 gallons. With it’s small size and a Footprint of less than 11 by 7 inches makes this protein skimmer a great choice for aquariums in this range due to the fact that sump space is typically limited.

The sleek and compact Reef Octopus Classic 110SSS in-sump protein skimmer supplies powerful filtration for aquariums up to 130 gallons where sump space may be limited.

The Reef Octopus Classic 110-S is constructed of high-quality acrylic that can be completely disassembled for cleaning. Equipped with the new Aquatrance pinwheel pump, it produces an ideal mix of water and air for optimum waste removal. A simple vented wedge valve output provides precision control and allows cleaned water to exit the skimmer below water for quiet operation. Also available in the larger Classic 150S model.

Internal model designed for in-sump use only. No feed pump required, skimmer draws water directly from sump.
