Attractive, Ultra Compact and Affordable Filtration
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 110SSS 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 150SSS model.
Internal model designed for in-sump use only. No feed pump required, skimmer draws water directly from sump.
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 110SSS compares
| Model | Pump | Rated for | Footprint | Height | Sump water depth |
|---|---|---|---|---|---|
| Classic 110SSS (this page) | Aquatrance 1000s, 9 W | Up to 130 gal | 6.1 x 7.87 in | 19.7 in | 7–8 in |
| Classic 150SSS | Aquatrance 2000s, 18 W | Up to 210 gal | 7.3 x 9.5 in | 20.9 in | 7–8 in |
| Regal 150SSS | VarioS 2-S DC | Up to 210 gal | 9 x 7.5 in | 23 in | 6–8 in |
| Classic 1000 HOB | Aquatrance 1000s, 9 W, mounted externally | Up to 130 gal | 8 x 3.5 in | 17 in | Hangs on the tank |
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 150SSS, the next size up with a 6" body for tanks up to 210 gallons, or the Classic 1000 HOB, a hang-on-back skimmer for tanks without a sump.

Expert buying guidance
Classic 110SSS 5" Internal Space Saving Protein Skimmer FAQs
What size tank is the Classic 110SSS rated for?
Up to 130 gallons with a light bioload, 90 gallons medium and 60 gallons heavy, excluding the sump.
Does the Classic 110SSS need a feed pump?
No. It is an in-sump skimmer that draws water directly from the sump. Reef Octopus recommends a sump water depth of 7 to 8 inches.
How big is the Classic 110SSS?
It has a 5" body, a 6.1 x 7.87 in footprint and stands 19.7 in tall. It runs an Aquatrance 1000s pinwheel pump at 9 W with about 420 lph of air draw.
Should I leave my protein skimmer on all the time?
Yes. In most reef tanks the skimmer runs around the clock. Pause it while you feed or dose so food and additives aren't skimmed straight out, then let it restart. On Regal skimmers the VarioS controller's 15 or 60-minute feed modes do this for you.
