Description
The OASE ProfiClear Premium Moving Bed Module is a professional biological filtration unit designed for use within the ProfiClear modular filtration system.
It forms the key biological stage of the system, working after mechanical filtration to process dissolved waste such as ammonia and nitrite.
Inside the chamber, moving bed media (typically K1-type material) is kept in constant motion using aeration. This movement maximises oxygen exposure and ensures continuous contact between beneficial bacteria and pond water.
This process creates a highly stable biological environment capable of handling heavy koi stocking and large pond systems.
The module is designed to be combined with ProfiClear drum filters and discharge components to form a complete high-performance filtration system.
Typical Applications
