The Reef Octopus Elite 220 SSS Protein Skimmer is a high-performance, in-sump filtration device designed to efficiently remove dissolved organic waste from saltwater reef aquariums. Utilizing advanced foam fractionization technology, it creates a dense column of micro-bubbles that attract and collect organic compounds, preventing their breakdown into harmful nutrients and significantly improving overall water quality and clarity for a thriving reef environment. This Elite series skimmer features a turbulence-reducing Super Cone body for optimal bubble contact time, powered by a safe and efficient 36V VarioS-6S controllable DC pinwheel pump. Users benefit from five energy-saving power settings, a detachable controller with multiple pause/feed modes (15 or 60 minutes), and a crucial safety float switch. Its robust construction includes solid cast acrylic and machined PVC, a professional open volute design, and a convenient “Twist & Lift” collection cup for easy maintenance. The unit has a footprint of 13.6″ x 11.2″ and stands 25.2″ tall, with a 9″ reaction chamber. Ideal for serious reef aquarists maintaining medium to large systems, the Reef Octopus Elite 220 SSS handles bioloads from heavy 300-gallon tanks to light 530-gallon setups. Its precise controllability via the VarioS pump and 0-10v input for third-party controllers makes it perfect for those seeking ultimate command over their filtration and seamless integration into advanced aquarium automation systems, ensuring unparalleled stability and health for demanding reef inhabitants.
