This Happet foam pad is a filter media block for keepers who need to replace or top up mechanical and biological media in freshwater, marine or pond filters. It is supplied as a 25 x 25 x 5 cm sheet, so it can be trimmed to match the chamber of a given filter.
Why it matters
- Medium-coarse structure: the 30 PPI density is listed as high, which means the foam holds fine suspended debris that would otherwise pass through the filter.
- Biological surface: the open cell structure gives nitrifying bacteria a colonisation area, which supports the biological cycle of the tank.
- Trimmable format: the 25 x 25 x 5 cm sheet can be cut to the dimensions of internal or external filter compartments.
- Two filtration roles: the same block serves as mechanical pre-filtration and as a biological media, so one product covers both functions.

What it works with
The foam is designed for freshwater and marine aquariums as well as pond systems, and it fits common aquarium and pond filters. Because it is cut to size, it can be adapted to different filter designs rather than being limited to one model. Use it in the mechanical stage to trap particles, or in the biological stage to host nitrifying bacteria.
