Varios 4 Circulation Pump

Reef Octopus VarioS 4 Aquarium Circulation Pump – Smart Flow Meets Everyday Reliability

If you’ve ever juggled noisy pumps, unpredictable flow, or a spaghetti mess of cords in your sump, the Reef Octopus VarioS 4 Aquarium Circulation Pump is about to simplify your life. This compact workhorse moves water efficiently, plays nice with controller setups, and—bless it—runs whisper quiet.

Whether you're feeding a calcium reactor, driving a return line, or setting up a closed-loop system, this pump delivers steady, controllable flow without the drama.

Why the Reef Octopus VarioS 4 Aquarium Circulation Pump Belongs in Your Setup

This isn’t your typical off-the-shelf aquarium circulation pump. It’s built with reefers in mind—people who need precise control, flexible installation, and equipment that doesn’t flinch when the power flickers.

Key Benefits:

• Max Flow: 1,050 GPH – enough for most medium to large reef setups

• Max Head: 14.7 ft – gets the job done for taller tanks or external sumps

• True 5-Speed Control: Adjust flow in real time based on what your tank actually needs

• Soft Start: No jolting surge—just a gentle ramp-up that won’t spook your fish

• Feed Mode: Pauses flow for 15 or 60 minutes (because no one likes chasing pellets across the tank)

• Ultra Quiet: Seriously—your protein skimmer will be louder

Bonus? It remembers your settings during power outages. No reprogramming, no panic.
