OCTO Classic 110-S Protein Skimmer
The OCTO Classic 110-S is a compact in-sump protein skimmer from Reef Octopus, designed for reef aquariums with limited sump space. It removes organic waste, proteins, and dissolved organics by generating a dense foam of microbubbles in a reaction chamber. Waste attaches to the bubbles and collects in the cup as skimmate.
It uses a simple, reliable AC pinwheel pump (no controller needed) and features a straight-body “Space Saver” design. The skimmer is made from high-quality cast acrylic and is praised for its quiet operation, ease of use, and good value.
Recommended Aquarium Size (excluding sump):
- Light bioload: up to 500 litres
- Medium bioload: up to 340 litres
- Heavy bioload: up to 230 litres
Features & Benefits:
- Ultra-compact Space Saver design — Small footprint frees up valuable sump real estate while delivering strong performance.
- Aquatrance 1000S pinwheel pump — Specifically engineered for protein skimmers; provides consistent air and water draw with low power consumption.
- Bubble-free outflow — Vented wedge valve and submerged output design minimize bubbles returning to the sump for cleaner, quieter operation.
- Removable turbulence — reducing bubble plate — Helps create a stable foam head and improves contact time between bubbles and organics.
- Tool-free maintenance — Skimmer body disassembles easily; quick-release neck for fast cup cleaning; fully accessible for thorough cleaning.
- Quiet and efficient operation — Low-wattage pump and silencer keep noise to a minimum.
- Solid acrylic construction — Durable, clear material that resists yellowing and allows easy visual monitoring of the foam column.
- No feed pump needed — Draws water directly from the sump, simplifying plumbing and reducing points of failure.
- Adjustable performance — Easy-to-tune gate/wedge valve lets you dial in the desired foam consistency (wet or dry skim).
