แล้วพบว่า การไหลของน้ำช้าลง อุดตัน ควรเปลี่ยนแผ่นกรอง เพื่อเพิ่มประสิทธิภาพการกรอง ให้กลับมาทำงานเหมือนใหม่
"EHEIM foam filter pad/Coarse filter pad" (white/blue)
Fine and coarse filter pads for mechanical and biological 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.

"EHEIM carbon filter pad" (black)
Fine and coarse activated carbon filter pads for adsorptive filtration
For adsorptive filtration – also for removal of harmful chemical substances (chlorine, remains of medical treatments etc.) – there are special activated carbon fine and coarse filter pads as a filter insert. Adsorptive filtration is usually only necessary in the start-up phase of the aquariums or after use of medication. The filter media should only be used for a short time (ca. 4 weeks) and then removed or replaced.
