The UltraZap pond filter box is a pre-filter chamber that sits between the pond and the main filter, catching big debris so your biological media stays clean for longer. Choose the standard 0.9m² or large 1.2m² box without base, or the combi filter box with base measuring 1250×800×850mm.

Fill the box with foam or filter brush to match your setup — it works equally well on garden ponds, koi systems and large aquarium or fish tank installations.
