The filter brushes consist of fine, wavy plastic bristles with an X-shaped structure. The eyelet at the top has a diameter of 20mm, the wire with the end cap is 3cm long at the bottom, so it can be fixed in a base plate or otherwise if desired.

Filter brushes can catch an extremely large number of particles (even the smallest particles) and, in contrast to other filter materials, do not clog.

The brushes have the advantage that they can be used both as a mechanical and, after a certain running-in period, as a biological filter medium.

Here you offer a very good settlement area for microorganisms.

With a salt content of more than 0.3% salt in the pond, corrosion can occur on the brush.

• Great for both biological and mechanical filtration
• Low unit cost
• Easy to clean
• Very effective at reducing foam filter cleaning
• Massive surface area for biological colonisation
