Description
The OASE ProfiClear Premium XL Moving Bed is a professional biological filtration chamber designed to work within the ProfiClear modular system.
It provides the second key stage of filtration after mechanical waste removal, supporting the breakdown of harmful ammonia and nitrite through highly efficient biological processes.
Inside the chamber, water flows through a large volume of moving bed media, typically K1-based material, which remains in constant motion. This movement ensures maximum oxygen exposure and continuous contact between beneficial bacteria and pond water.
The result is a highly stable and efficient biological environment capable of handling heavy koi stocking levels and large pond systems.
This unit is designed to be paired with ProfiClear drum filters, forming a complete high-end filtration solution.

- Air is injected into the chamber to keep media in motion
- K1 media provides surface area for beneficial bacteria
- Bacteria break down ammonia and nitrite
- Clean biologically processed water exits the chamber
Where This Product Sits
The XL Moving Bed is the biological heart of the ProfiClear system.
It sits within:
- ProfiClear modular filtration systems
- High-end koi pond installations
- Professional pond filtration setups
It is NOT:
- A standalone pond filter

It must be paired with:
- ProfiClear drum filter (DF-XL)
- Air pump system for media agitation
- Pump or gravity-fed circulation system
Installation
- Installed as part of modular ProfiClear system
- Requires connection to drum filter module
- Requires aeration system (air pump)
- Installed in technical filter chamber
Maintenance
- Low maintenance biological chamber
- Periodic inspection of media movement
- Air system maintenance required
- Occasional cleaning of chamber base
- Check bacterial activity balance
