Reef Octopus VarioS 6S Controllable Skimmer Pump — Complete Guide, Benefits & Comparison

Whether you’re building a new reef system or upgrading your existing filtration setup, the Reef Octopus VarioS 6S Controllable Skimmer Pump stands out as a top choice for advanced aquarists. With controllable speed, quiet performance, and premium engineering, this pump delivers superior skimming for medium to large aquariums.

In this article, you’ll learn what it is, why it matters, its key benefits, how it compares with other options, and why it’s worth investing in.

What Is the Reef Octopus VarioS 6S Controllable Skimmer Pump?

The Reef Octopus VarioS 6S is a DC controllable skimmer pump designed specifically for protein skippers in reef and marine aquariums. Unlike fixed-speed AC pumps, the VarioS 6S allows you to fine-tune the water flow, creating precise foam production that vastly improves nutrient export and water clarity.

This pump is commonly used in higher-end protein skimmers from Reef Octopus and other compatible brands due to its strong airflow, customizable performance, and dependable build.

Why Choose a Controllable Skimmer Pump?

Traditional skimmer pumps operate at a fixed speed — which means you compromise between too much airflow or too little foam quality. A controllable DC pump, like the VarioS 6S, gives you the best of both worlds:

Adaptability: Adjust speed based on tank saturation and bio-load

Efficiency: Run quieter with lower energy use

Better Skimming: Generate optimal bubble size and consistency

For reef keepers who care about water quality and noise levels, a controllable DC skimmer pump is one of the most impactful upgrades you can make.

Key Benefits of the VarioS 6S

1. Adjustable Speed for Precision Performance

The greatest advantage of a controllable pump is the ability to dial in exactly the amount of water and air movement you want — from gentle skimming to aggressive foam production.

This makes it ideal for:

High bioload systems

Reefs with heavy feeding schedules

Aquariums with sensitive livestock

2. Ultra-Quiet Operation

Thanks to its DC motor and balanced impeller design, the VarioS 6S runs significantly quieter than many standard AC pumps — a major benefit for home and office aquariums where noise matters.

3. Enhanced Energy Efficiency

Running at controlled speeds means you’re not wasting power. The pump uses only what’s needed, reducing long-term electrical costs compared with non-controllable alternatives.

4. Improved Skimming Quality

The specialized impeller and adjustable airflow result in dense micro-bubbles that excel at extracting dissolved organic waste — leading to:

Clearer water

Lower nitrates

Better overall tank health

5. Built-for Saltwater Durability

Reef Octopus builds its pumps with high-quality materials that resist corrosion and wear in marine environments. The VarioS 6S is designed for longevity — an investment that continues to pay off over years of reefing.

How to Choose the Right Skimmer Pump

When selecting a pump like the VarioS 6S, consider these factors:

Tank Size

The VarioS 6S is best suited for medium to large reef systems (typically 150+ gallons), depending on skimmer body and bioload.

Skimmer Compatibility

Confirm that your protein skimmer model supports a VarioS-series pump. Reef Octopus units are usually compatible, and many third-party skimmers can adapt with the right plumbing.

Noise Expectations

If your aquarium is in a living room or quiet space, a controllable DC pump like the VarioS 6S is worth the investment for its whisper-quiet performance.

Budget vs Long-Term Value

While DC controllable pumps cost more initially, they last longer, run more efficiently, and can improve tank stability — often saving money over time.

Conclusion — Why the VarioS 6S Is Worth It

The Reef Octopus VarioS 6S Controllable Skimmer Pumps are distributed by CoralVue her in the US and there support is very good. The pump isn’t just another accessory — it’s a performance upgrade for serious reef keepers. With adjustable speed, energy efficiency, quiet operation, and superior skimming quality, it elevates your filtration system without compromise.
