Why we chose it

The named U3 fit decides this one. The foam is made for that chamber and its first mechanical filtration stage, so there is less guesswork than adapting a generic pad.

Specifications

Brand: Fluval

Full description

The first thing a filter has to deal with is the visible debris moving through the water. These pads are shaped for the Fluval U3 Underwater Filter chamber, so that stage can catch large particles before they pass further into the filtration system.

The pad is custom-made for the chamber to prevent debris bypass. Its pore size is intended to allow efficient water flow, less clogging and long-lasting filtration, and the listing says it suits freshwater, marine or reptile environments.
