Fluval U1 Foam Pad captures large particles and debris for effective mechanical filtration, the crucial first stage in the filtration process.

It is custom-made to fit perfectly inside the filter chamber to prevent debris bypass. The foam pad has a pore size that allows efficient water flow, less clogging and long-lasting filtration. Suitable for freshwater, marine or reptile environments.
