The Fluval U2 Foam Block dislodges large particles to provide effective mechanical filtration, which is the critical first step in the filtration process.
Custom designed, the Fluval U2 foam block fits snugly into the filter chamber to keep debris out. The pore size prevents clogging and allows for consistent water flow and long-lasting filtration.
