Reef Octopus Classic 110-S Space Saver Protein Skimmer
The Reef Octopus Classic 110-S (SKU: CLSC-110S) is the perfect solution for marine hobbyists who need big filtration capacity but are dealing with highly restricted sump real estate. Rated for aquariums up to 130 gallons, this "Super Space Saver" model achieves its tiny footprint by mounting the highly efficient Aquatrance 1000s pinwheel pump directly inside the 5-inch reaction chamber. This intelligent design allows you to fit a true 5-inch skimmer into small sump compartments that would normally only accommodate lower-performing, undersized equipment.
Despite its compact build, the Classic 110-S compromises nothing on performance. It features a hand-crafted, high-grade cast acrylic hybrid cone body that minimizes internal water turbulence. This allows the micro-bubbles generated by the Aquatrance pump to rise steadily, forming a dense, concentrated foam column that carries dissolved organics cleanly into the collection cup. Complete with a turbulence-reducing bubble plate diffuser and a precision output gate valve, the Classic 110-S provides the ideal balance of space-saving geometry and industrial nutrient export.
