Eheim aquaball 180 / 60 filter basket expansion

This is a filter basket for eheim aquaball systems. You can use every filter medium you want to use. The part is a little larger than the original filter basket. For water tight fit tape the bottom of your original filter basket with isolation tape or similar tape. I use this for my 120 L aquarium because the original eheim aquaball 180 was to weak for my setup. (I use filter-cotton)
