They are designed to capture and remove larger debris and particles from the water as it passes through the filter. The bristles of the brush provide a textured surface that traps leaves, twigs, and other debris, preventing them from entering the deeper layers of the filtration system.

By capturing these larger particles, they help prevent clogging in other filter media. This contributes to maintaining water clarity, reducing nutrient levels, and supporting a healthier pond environment. Regular cleaning of the filter brushes is necessary to ensure their continued effectiveness in trapping debris.

Black Knight

Black Knight filter brushes are the best selling filter brush in the world. Black Knight brushes are made from high quality hydrotech polypropylene that has been twisted on to two stainless steel wires. A loop is then added at the top of the brush to allow for easy hanging and a rubber cover is added to the bottom of the brush for safety. Black Knight filter brushes are primarily used as mechanical filtration in pond filter systems to remove larger solids and also to provide a level of biological filtration. They are lightweight, easy to clean and do not need replacing. We recommend that when using Black Knight brushes in a filter system, they are overlapped by upto 50mm(2"). Overlapping increases the brushes biological and mechanical efficiency. The filter brushes can be placed in the filter vertically or horizontally.
