Product Description

When your filter foam starts to clog or break down, water flow drops and clarity suffers. These Filter Foam Sets — Cut to Match (CMF) give you fresh mechanical filtration that you trim to fit your filter bay.

Available in three generous sheet sizes to suit a wide range of pond filters.

Why it’s a good fit

  • Cut to Match (CMF) – trim to suit your filter chamber
  • Restores mechanical filtration performance
  • Helps remove solid waste and debris before the bio stage
  • Ideal for replacing worn or compacted foam

Fresh foam improves water flow and helps protect your biological media from clogging.

Where it fits in your system

Typical filter flow:

Pump → Mechanical foam → Biological media → Return

Position foam before your bio stage to trap solids early and keep the system running efficiently.

Installation tips

  • Measure your filter bay before cutting.
  • Use a sharp knife for clean, straight edges.
  • Rinse foam in pond water before first use.
  • Replace when foam no longer springs back after cleaning.

Maintenance note

Clean foam regularly in pond water, not tap water, to protect beneficial bacteria living on the surface.

A simple upgrade that keeps water moving and filters working properly.
