Reef Octo BioReact Bio Churn Reactor

About the Reef Octo BioReact 120 Bio Churn Reactor

The Reef Octo BioReact 120 Bio Churn Reactor is designed for marine aquarium filtration, helping maintain biological media in motion to support efficient bacterial colonisation and nutrient processing. Reactors of this type are commonly used with biopellets or other compatible biological media to support the breakdown of organic waste compounds in reef systems.

The reactor's churning action helps keep suitable media moving rather than allowing it to compact into a solid mass. This promotes water contact with the media and helps reduce channeling, where water passes through only a small portion of the media bed.

It is intended for use as part of a properly maintained filtration system, typically connected to a sump. The reactor must be operated with media and flow rates compatible with the manufacturer's recommendations. Excessive tumbling can damage media, while insufficient flow can allow it to clump together.

Frequently Asked Questions

What does the BioReact 120 reactor do?

It keeps biological media moving to encourage bacterial growth and help reduce nitrate and phosphate levels in marine aquariums.

Does it come with a pump?

Yes. The BioReact 120 includes an Aquatrance AQ-1200 circulation pump.

What media can I use?

Reef Octopus recommends its Bio Spheres biopellet media. Check compatibility before using alternative media.

How does the churning action help?

The movement helps prevent media from clumping and reduces channeling, improving contact between the water and the media surface.

Can I use it in a freshwater aquarium?

It is primarily designed for marine nutrient management. Confirm the suitability of the chosen media and intended application before using it in freshwater.

How often does it need cleaning?

Inspect the reactor and pump regularly. Cleaning frequency depends on the media, accumulated debris and operating conditions. Follow the manufacturer's maintenance instructions.

Common Mistakes

• Adding too much media and restricting its movement.

• Running the reactor with insufficient flow, allowing media to clump.

• Setting excessive flow that tumbles or damages the media.

• Failing to inspect the pump and reactor inlet for blockages.

• Increasing biopellet quantities too quickly, potentially destabilising nutrient levels.

• Assuming the reactor alone will correct every nutrient problem without regular water testing.
