Black Knight Filter Brushes

Offering a full range of Black Knight Filter Brushes you won't find better quality brushes anywhere; ours are high density and we use top quality materials.

Black Knight Filter brushes are designed as a pre-filter for removing coarse waste and/or as a biological filter medium. Any design of filtration chamber will suit these brushes and they are easily removed for cleaning.

Black Knight brushes are by far the most efficient and user-friendly product for removing suspended particles from your pond water.

There is also a special crimping effect on our filaments and this is designed to maximise the surface area for the colonisation of beneficial nitrobacter and nitrosomonas bacteria.

Black Knight Filter Brushes are ideally positioned in rows when they overlap each other by 2 - 5cm.

How do I layout the Filter Brushes:

There are three main ways and they are explained below.

1. Single interlocked

"Simple to build, good particle removal"

This design is very simple to construct and maintain, yet offers a high degree of particle removal. It is ideal as a pre-filter before any biological chamber. Used in this way, the efficiency of the biological chambers will be enhanced and the overall maintenance time will be reduced.

2. Double interlocked vertical flow

"Excellent combination of mechanical and biological performance"

This design allows a superb combination of mechanical and biological performance, yet is still simple to build and maintain. It can be a stand-alone filter or any number of these can be linked in series. In order to achieve the most efficient removal of the bulk of the waste matter in a multi-chamber filter system, we recommend that the water should pass through a horizontal flow settlement chamber before entering the vertical flow chambers.

3. Horizontal combination

"The most efficient and user-friendly design of filter.Suitable for gravity feeding"

This is the ultimate settlement chamber. It works best in a gravity-feed configuration where the water is slowed by the standpipe so that there is the minimum amount of turbulence in the settlement area, thus the greatest amount of waste is allowed to settle.

The primary brushes can be removed as necessary for cleaning and the secondary brushes will trap the very finest particles.
