Theiling Compact Rollermat: Ditch the filter socks. Roll up your reef tank waste automatically!

Say goodbye to filter socks and say hello to crystal clear tank water. Theiling Compact Rollermat is an automatic mechanical filtration solution that easily sets inside your sump and filters water as it drains from your display down into the sump. The built in motor is triggered by an internal float switch that automatically advances the filter material as it becomes clogged releiveing the need for any sort of regular maintenance. Simply remove and replace the exhausted filter fleece with a clean roll and never touch another filter sock again!
