UltraZap cylindrical filter brush for the first stage of pond filtration, in 400, 800 and 1200mm lengths with a 200mm diameter. The dense bristles trap leaves and large debris before they reach your biological media, and their filaments give nitrifying bacteria extra surface to grow on.

Hang them in a pre-filter or vortex chamber, or across a filter box — they suit garden ponds, koi setups and large fish tank or aquarium filtration.

Good to know:

– 200mm diameter cylindrical brush
