Pond Filter Brushes Filter Media from Black Knight

Black Knight filter brushes are the best-selling filter brush in the world.

Black Knight brushes are made from high-quality hydro tech polypropylene that has been twisted onto 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 up to 50mm(2"). Overlapping increases the brush's biological and mechanical efficiency. The filter brushes can be placed in the filter vertically or horizontally.
