Reef Octopus VarioS-6 DC Circulation Pump
The Reef Octopus VarioS-6 brings advanced water movement technology to serious reefkeepers. Designed with safety, flexibility, and performance in mind, this controllable DC pump is ideal for powering sumps, filters, reactors, and closed-loop systems—giving aquarists complete command over flow rates and automation.
Why Choose the VarioS-6?
- DC Power Advantage
Unlike traditional AC pumps, the VarioS-6 runs on low-voltage 36V DC power for enhanced energy efficiency, reduced heat, and safer aquarium operation. - Quiet & Durable Design
Built with a high-quality ceramic shaft and propeller bearing, the VarioS-6 reduces internal wear and extends pump life - all while operating whisper-quiet. - Smart Controller Included
The included controller lets you easily dial in flow with 5 speed settings, and adds critical safety & automation features without the need for external modules.
Intelligent Control Features
- Float Switch Support (Included)
Automatically shut down the pump during high or low sump water levels using the included float switch - no extra equipment needed. - Feed & Maintenance Modes
Temporarily pause the pump for 15 or 60 minutes, perfect for feeding sessions or water changes. - Third-Party Controller Compatibility
Integrates seamlessly with external aquarium controllers like Neptune Apex or Reef Angel using a 0–10V input. Program advanced flow schedules directly through your system's control hub. - Soft Startup
Pump gently ramps up over 10 seconds to reduce system shock and wear on equipment. - Flexible Output Positioning
The rotating volute allows output direction in 90° intervals for vertical or horizontal plumbing setups.
