Black Knight Filter Brush provides biological & Mechanical pond water filtration and used as mechanical filtration components in pond filtration systems. 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.
