Reef Octopus In Sump 10" Protein Skimmer from Reef Octopus - with a controllable VarioS DC pumps to process more or less water, depending on your setup.

  • Footprint - 11.4" x 7.5″
  • Height - 22.6″
  • Recommended Water Height: 6"-8"


Reef Octopus Regal Skimmers now incorporate the new VarioS S pinwheel series of pumps. The new pumps are DC powered allowing for several advantages over traditional AC style pumps. The VarioS pumps can be fully controlled by a 3rd-party controller or through the included control unit. With 5 different preset speeds, and multiple feed modes, you can fine-tune Regal skimmers for superior performance on your particular system.


Internal protein skimmers that have the pump mounted externally will normally be more efficient than a space saver model (internally mounted pump) due to the fact that there is more room in the skimmers reaction chamber and less overall turbulence. They do require a bit more space but if your sump can fit a protein skimmer that has an externally mounted pump you will see much better results.

Product Questions

Is this compatable with ozone?
Question by: Travis Oglsbee on Mar 18, 2022, 8:45 PM
Travis, thanks for the question! It is not recommended for ozone!

Would you recommend the 150int or 200 sss for a 133 gal display? It's a WB 170 so I'm limited on skimmer space. Thanks
Question by: Steven Fensterer on Dec 4, 2021, 3:33 PM
Thank you for reaching out. It really depends on your stocking level for the system. If you have a heavy bioload, I would go with the 200SSS but if you are light to medium light, the 150 INT would be a good option. The INT is easier to service but that causes it to take up more space.

Will this fit in the Trigger Systems Ruby 20 Cube Sump?
Question by: Matt Nielsen on Dec 28, 2017, 5:37 PM
Thanks for reaching out to BRS!

I would say this skimmer would fit, but, it would be tight. The skimmer has a footprint of 11.4" x 7.5" and the skimmer/drain section of the sump is 11.6" x 12". Have a great day!
