Overview

The Reef Octopus Classic 2000-HOB is a powerful hang-on-back protein skimmer engineered for marine aquariums up to 200 gallons. With a slim profile and externally mounted Aquatrance 2000s pinwheel pump, it’s ideal for systems without a sump or where cabinet space is limited. This external pump design also prevents heat transfer to the tank and simplifies maintenance.
