AQUANEAT Aquarium Filter Sponge Foam, 2-Pack 40 PPI Cut-to-Fit Pads, 36 x 12 x 1 in

AQUANEAT aquarium bio sponge filter media is a cut-to-fit, open-cell foam pad for aquarium and pond filtration, supplied as two 36 x 12 x 1 in (91.44 x 30.48 x 2.54 cm) pads with a 40 PPI structure.

• Two foam pads — prepare filter media for multiple sections or keep a spare ready.
• 40 PPI open-cell foam — offers a large inner surface area for filtration.
• Cut-to-fit format — size the pad for a filter, sump or DIY HMF project.
• Captures large waste particles — helps maintain water flow and reduce the chance of clogging.
• Dense, tear-resistant structure — supports cleaning and repeated reuse.
• Vacuum-packed foam — expands to full size after 10 minutes of water immersion.

Filter media needs to fit the equipment you use while helping catch larger debris before it restricts water movement. AQUANEAT’s sheet format lets aquarium and pond keepers trim the foam to suit a range of filtration setups, including use as a pre-filter. The foam arrives vacuum-packed, so allow it to expand in water before cutting it to the required shape.

What filters can this AQUANEAT sponge pad fit?

AQUANEAT sponge filter media can be cut for use as a pre-filter in aquarium or pond filters, sumps, wet/dry filters, canister filters and power filters, as well as DIY HMF projects. Its sheet form lets you adapt the media to the filter area you need to cover.

• Trim the foam to fit the intended filter space.
• Use it as pre-filter media to catch larger bits of waste.
• Suitable for aquarium and pond filtration setups.

How does the open-cell foam support filtration?

The 40 PPI open-cell structure provides a larger inner surface area for filtration. As water passes through the pad, the foam traps large waste particles, helping water flow through the filter and lowering the chance of a clog.

• Open-cell construction creates inner surface area for filtration.
• Captures larger debris rather than leaving it to build up in the filter.

How do you prepare and reuse the AQUANEAT foam?

Immerse the vacuum-packed foam in water for 10 minutes; it expands to full size. The dense foam structure helps prevent tearing, making the pad easy to clean and reuse for continued filter-media use.

• Let the pad expand in water before trimming it.
• Clean and reuse the foam; its dense structure resists tearing.

AQUANEAT bio sponge filter media suits aquarium and pond keepers who want adaptable foam for pre-filtration across different filter types or a DIY HMF setup. It is a sheet to cut to the filter space, rather than a pre-shaped filter insert. For buyers who need reusable, cut-to-fit media that catches large debris, its open-cell foam format and 40 PPI structure provide the fit and filtration features.
