Eheim Aquarium pre-filter

EHEIM Pre-filter. This pre-filter retains most of the coarse dirt before the water reaches the lui-même filter (external filter). The pre-filter is installed in place of the suction pipe. Its base is located in the aquarium's sol. Water is drawn in through the large-surface filter basket. This is lined with filter material, which is easy to clean and replace. For cleaning, simply remove the basket using plant tweezers, for example.
