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 - 16.5″ x 11″
  • Height - 24″
  • Recommended Water Height: 7"-8.5"


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.
