VarioS 4 Circulation Pump

Reef Octopus VarioS 4 Aquarium Circulation Pump—Everyday Reliability With the Power of Smart Flow

If your sump has ever suffered from noisy pumps, unpredictable flow, or a spaghetti mess of cords, the Reef Octopus VarioS 4 Aquarium Circulation Pump is going to make your life easier. This pint-sized workhorse moves water efficiently, plays well with controller setups, and—bless it—runs whisper-quiet. This pump provides a constant, controllable flow without the drama, whether you are feeding a calcium reactor, running a return line, or a closed-loop system.

Why The Reef Octopus VarioS 4 Aquarium Circulation Pump Should Be In Your Setup

This model is not your average off-the-shelf aquarium circulation pump. It is designed for reefers, those who require precise control, adaptable installation, and gear that doesn’t blink when the power falters. Main Benefits:

• Max Flow: 1,050 GPH – for most medium to larger reef setups.
• Max Height: 14.7 ft – does the job for taller tanks or external sumps
• True 5-Speed Control: Flow is adjusted in real time to the actual needs of your tank
• Soft Start: No jolting surge, just a gentle ramp-up that won’t startle your fish
• Feed Mode: Stops the flow for 15 or 60 minutes (because nobody likes chasing pellets around the tank)
• Ultra Quiet: Your protein skimmer is actually going to be louder

Bonus? It retains your settings during power outages. No fear, no reprogramming.

All Reef Octopus pumps now have an extended warranty: 5 years on pump bodies, 3 years on controllers, and 1 year on rotors and other parts. Valid for purchases made on or after January 1, 2025. Full terms are available on CoralVue’s warranty page.
