Octo Regal 200EXT Recirculating Protein Skimmer

High-performance External Recirculating Protein Skimmer

The Reef Octopus Regal 200-EXT is a premier external recirculating protein skimmer engineered for large reef systems where in-sump space is unavailable or an external configuration is preferred. Featuring an 8-inch wine-glass body, the 200-EXT utilizes a recirculating design, meaning the VarioS-4S DC pump focuses exclusively on shredding air and water within the body, while a separate feed pump (sold separately) dictates the flow-through rate. This allows for absolute control over contact time, leading to superior organic waste removal.

The Regal EXT series combines industrial-grade performance with the intelligence of controllable DC technology. The included VarioS controller manages the pump's speed and includes a waterproof connection for the integrated float switch safety sensor. This feature is vital for external installations, as it prevents messy overflows by instantly cutting power to the skimmer if the waste level in the cup becomes too high. With its high-quality cast acrylic construction and precision gate valve for water level control, the Regal 200-EXT is the professional choice for serious aquarists looking for a clean, external filtration solution.

Key Features:

• Recirculating Design: Allows you to control the feed rate independently of the skimmer's internal mixing for maximum efficiency.

• VarioS-4S Controllable Pump: High-flow DC pinwheel pump with 5 speed presets and a "soft start" for stable performance.

• External Safety: Integrated float switch prevents collection cup overflows—essential for out-of-sump installations.

• Wine-Glass Body: The iconic 8-inch tapered shape stabilizes foam as it rises toward the neck for a cleaner "dry" skimmate.

• 0-10V Integration: Ready for connection to third-party controllers for advanced automation and remote monitoring.
