 Filter brushes are made from the very highest quality polypropylene twisted into two stainless steel wires to form a cylindrical brush with a loop at one end for hanging. The other end is capped with a plastic knob for safety.
They last indefinitely and are the easiest to use, most efficient and most cost-effective pond filter medium you can buy.
Filter brushes are used in filtration systems in fish farms, hatcheries, public aquaria, domestic fish ponds and research institutes in this country and abroad. |
