Footprint: 8.8" x 3.5" | Height: 17"
Pump: Reef Octopus Aquatrance 1000s
Ultra Slim Hang-On-Back Skimmer
The compact Reef Octopus Classic 1000-HOB is a proverbial favorite amongst hang-on back protein skimmer users providing beneficial filtration for aquariums up to 130 gallons.
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 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.

How the Classic 1000 HOB compares
| Model | Pump | Rated for | Footprint | Height | Sump water depth |
|---|---|---|---|---|---|
| Classic 1000 HOB (this page) | Aquatrance 1000s, 9 W, mounted externally | Up to 130 gal | 8 x 3.5 in | 17 in | Hangs on the tank |
| Classic 110SSS | Aquatrance 1000s, 9 W | Up to 130 gal | 6.1 x 7.87 in | 19.7 in | 7–8 in |
SSS vs INT: on SSS (space-saving) models the pump sits under the body for a smaller footprint; on INT models it sits beside the body. Regal vs Classic: Regal skimmers run a VarioS DC pump with a controller (5 speeds, 15 or 60-minute feed modes, float switch safety and a 0-10V input), while Classic skimmers run an Aquatrance pinwheel pump with no speed controller.
Not to be confused with: the Classic 110SSS, an in-sump skimmer with a similar rating for tanks that have a sump.

Classic 1000 HOB Protein Skimmer FAQs
What size tank is the Classic 1000 HOB rated for?
Up to 130 gallons with a light bioload, 80 gallons medium and 60 gallons heavy.
Where does the pump go on the Classic 1000 HOB?
The Aquatrance 1000s pinwheel pump mounts externally, which keeps the skimmer slim. The skimmer has an 8 x 3.5 in footprint and stands 17 in tall.
Is a hang-on-back skimmer right for my tank?
A hang-on-back skimmer is a good fit when your tank has no sump. Check that you have room behind the tank for the 8 x 3.5 in footprint and 17 in height before you buy.
Do protein skimmers remove copepods?
A skimmer can pull out some free-swimming pods, but in an established tank most copepods live in the rock, sand and refugium, so the effect on the population is small.
