Simple to Operate Hang-On-Back Skimmer

The Classic 100-HOB is a proverbial favorite amongst hang-on back skimmer users capable of filtering aquariums up to 105 gallons. The Classic 100-HOB features an easy to install and operate design in which the pump is mounted inside the aquarium.

To install, simply place the skimmer on the back of the aquarium, mount the pump in place, adjust the intake strainer and it is ready to skim. The Reef Octopus Classic 1000-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.

Bioload Handling

The bioload of an aquarium refers to its ability to process waste in proportion to tank volume. Protein skimmers work best when properly matched with the bioload of the system.
