Burtons FB 1100 Bio Chamber

Burtons FB 1100 Bio Chamber

Large moving bed biological filter chamber designed to significantly increase biological filtration capacity in pond filtration systems.

The Burtons FB 1100 Bio Chamber is a large and highly effective moving bed biological filter designed to increase the biological filtration capacity of pond filtration systems. Burtons Aquatics designs and manufactures this robust bio chamber in the UK, ensuring excellent build quality and long term reliability.

Biological filtration plays a vital role in maintaining stable pond water conditions. As fish produce waste and organic debris breaks down, harmful compounds such as ammonia and nitrite enter the water. Beneficial bacteria colonise biological filter media and convert these compounds into less harmful substances. As a result, the pond remains safe and healthy for fish.

The FB 1100 Bio Chamber provides space for up to 200 litres of moving bed filter media. When combined with aeration, the media tumbles freely inside the chamber. This movement creates a highly oxygenated environment where beneficial bacteria can efficiently process waste.

The chamber has a maximum flow rate of 20,000 litres per hour. However, the recommended operating flow rate is between 10,000 and 12,000 litres per hour. Therefore, the FB 1100 Bio Chamber is well suited to medium and large pond filtration systems. In addition, it can also be installed as an additional biological stage after a drum filter.

Designed for Moving Bed Biological Filtration

The Burtons FB1100 Bio Chamber is designed specifically for moving bed biological filtration systems.

Inside the chamber, air stones agitate the biological filter media using a steady supply of air. As a result, the media remains suspended and moves freely within the chamber. At the same time, the movement constantly exposes the bacterial biofilm to oxygen rich water.

As the media circulates and tumbles, beneficial bacteria remain highly active. Consequently, the bacteria can process dissolved waste more efficiently. In addition, the constant movement helps maintain a thin and active biofilm layer. This prevents the media from clogging and keeps the filtration system working efficiently.

Therefore, the moving bed process supports strong biological filtration and helps maintain clear and healthy pond water.

Optimised Media Performance

The FB 1100 Bio Chamber can hold up to 200 litres of fluidised biological filter media.

For optimal filtration performance, Burtons recommends using a mixture of Bio Flo+ Media and Bio Tube Media. Because the two media types have different shapes and structures, they interact as they circulate within the chamber.

As the media moves, the pieces gently collide and bounce against each other. This increases the tumbling or boiling motion inside the filter chamber, improving oxygen distribution and circulation.

The increased movement supports more active bacterial colonies and helps maintain a healthy biofilm. As a result, the filter can process waste efficiently while maintaining stable water conditions.

Large Capacity Design for Higher Flow Systems

The FB 1100 Bio Chamber is designed for pond filtration systems that require increased biological capacity.

Because the chamber holds up to 200 litres of filter media, it provides a large surface area for beneficial bacteria to colonise. This makes it ideal for larger ponds, koi ponds and filtration systems handling heavier fish loads.

The flat bottom design encourages strong circular water movement within the chamber. This helps keep the media in constant motion and prevents waste from settling within the tank.

As a result, the entire volume of filter media remains active and fully involved in the biological filtration process.

Recommended Air Pump

To operate a moving bed biological filter effectively, the filter media must remain constantly suspended and tumbling within the chamber. This requires a reliable air pump capable of producing sufficient airflow to create a strong boiling motion inside the filter.

For the Burtons FB1100 Bio Chamber we recommend using a Charles Austen ET100 Air Pump or a Charles Austen ET120 Air Pump. These pumps provide strong airflow which helps keep the biological media fully fluidised while ensuring the bacteria receive plenty of oxygen.

Using the correct air pump ensures the filter media circulates freely inside the chamber. As a result, beneficial bacteria remain highly active and the biological filtration stage can efficiently break down ammonia and nitrite within the pond.

The Charles Austen ET range is well known for reliability, energy efficiency and quiet operation, making it an excellent choice for pond filtration systems.
