Quick Overview

Reef Octopus Recirculating External 7" Protein Skimmer from Reef Octopus - with a controllable DC pump to process more or less water, depending on your setup.

  • Rated for tanks up to 300 gallons

  • BRS recommended for tanks up to 200 gallons

  • DC-3500s controllable pump with 5 presets and a feed mode

The hybrid cone design reduces and stabilizes foam production resulting in less turbulence in the neck area and more time for the organics to rise and collect.
