Fine/coarse filter padsEHEIM fine and coarse carbon pads consist of specially textured materials and perform a number of functions in the filter layering of EHEIM Internal filters. Depending on which type, they combine mechanical, biological und adsorptive filtration.
The porous material becomes evenly soaked with water and traps large and small dirt particles. After a short start-up period purification bacteria, which provide intensive biological decomposition of harmful substances, colonise the specially structured foam.
The fine and coarse filter pads are reusable many times over. To clean them simply rinse and squeeze out, so that the bacteria cultures are not completely destroyed.
