Classic 110-INT Protein Skimmer

The Reef Octopus Classic 110-INT Protein Skimmer is the in-sump entry point to the Classic Series, built to sit inside a standard sump rather than hang on the tank. Its cone-shaped cast acrylic body and needle-wheel pump combine for long bubble contact time in a compact footprint, exporting dissolved organics as concentrated skimmate before they ever cycle into nitrate or phosphate.

• Best for: reef and mixed saltwater systems with sump capacity, typically up to 150 gallons
• Setup: in-sump, vertical cone body
• Pump: needle-wheel pinwheel pump, self-priming
• Maintenance: gate-valve water level adjustment for dialing in wet vs. dry skimmate

The 110-INT is a common recommendation for hobbyists moving from a HOB skimmer into their first sump build — it delivers noticeably more consistent skim quality once water level and air intake are dialed in, and the cone shape keeps the footprint small in tight sump compartments.

Compatible replacement parts: Classic 110 series needle-wheel pumps, neck extensions, and collection cups.
