Koi and pond filter maintenance made straightforward.

These cylindrical filter brushes are designed to work alongside pond skimmers and filtration systems. The set includes 10 brushes, giving you spares for regular cleaning cycles or multiple filter chambers.

What you're getting:

• 10 filter brushes per pack

• Three length options: 30cm, 40cm or 50cm (diameter 11cm)

• Available in green or black

• High-density bristle construction for debris removal

• Fits standard pond filter housings and aquarium tank systems

How it works:

Insert the brush into your filter chamber or skimmer housing. The bristles trap suspended solids, algae and waste — turn or agitate gently to dislodge material, then rinse. Regular brushing extends the life of your filtration media and maintains water clarity.

Compatibility:

These are universal replacement brushes. Measure your existing filter chamber depth before ordering to confirm the right length. Fits most pond filters and aquarium tank systems with 11cm-diameter openings.

Delivery and returns:

We dispatch within 2–3 working days. Standard UK delivery takes 7–14 days; express options available at checkout. If the brushes arrive damaged or don't fit your filter, simply return them within 30 days for a full refund. We're here to help via eBay messages if you have questions about size or fitment.
