OCTO Classic SSS 110-Protein Skimmer
OCTO Classic 110-S — Choose performance that fits your reef
A straight-body, space-saving in-sump skimmer with an Aquatrance pump.
François Neo’s recommendation
A protein skimmer should match your aquarium’s population, feeding routine and actual water volume. I look at air intake in relation to the system, rather than choosing a larger body by default. Compare the specifications below with your sump space and your intended livestock before selecting this model.

Plan for installation and service
For in-sump installation. Check the chamber dimensions and recommended operating depth, then allow extra clearance to lift out the collection cup and access the pump. The listed footprint and height do not include the extra room needed for maintenance.
Do not select solely from the maximum volume rating. Tell us your water volume, fish and coral plans, feeding routine and available sump space so we can discuss a suitable fit.
