Filter Wool

If fine particles are slipping through your filter and dulling water clarity, Filter Wool provides a simple, effective polishing stage.

Designed for mechanical filtration, filter wool traps fine suspended solids before they return to the pond. It’s commonly used as a final stage in box filters, multi-bay systems and top trays.

What it does

• Captures fine particles and debris
• Improves water clarity
• Acts as a polishing stage after brushes or foam
• Suitable for most pond filter systems

Placed after coarser media, it catches the smaller waste that other stages miss.

How to use

• Cut to size to fit your filter bay or tray
• Position after coarse mechanical media
• Replace or rinse when flow reduces

Avoid compressing too tightly, as this can restrict flow and increase maintenance.

Maintenance Tips

• Check regularly during peak feeding season
• Rinse in pond water if reusing
• Replace when fibres break down or clog excessively

Filter wool is a low-cost way to improve clarity and protect your biological stage — especially useful during heavy feeding or after pond cleaning.
