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 benefical nitrobacter and nitrosomonas bacteria.
