Black
Knight filter brushes are made from the very highest quality Hydrotek
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.
Our
brushes are used in filtration systems in fish farms, hatcheries,
public aquaria, domestic fish ponds and research institutes
in this country and abroad. No other filter medium is as widely
used or has been as extensively tested and proved.
