Black Knight Koi Spawning Brushes 16"x 8"

The highest quality Hydrotek polypropylene is twisted into two stainless steel wires to create the cylindrical Black Knight filter brushes, which include a loop at one end for hanging. For safety, the other end is sealed off by a plastic knob. They are the simplest, most effective, and most affordable pond filter medium you can purchase, and they last forever.
