Ehiem - Aquaball 45
The Eheim internal filters are a fantastic product as they are a completely flexible module system with a spherical head. The round pump head sits in a ball joint.
This enables adjustment of the outflow direction, whle the flow rate is set at the output regulator. The air supply is dosed via the new Power Diffusor. And during all of this the filter remains in its position.
The filter is simply taken out of the holder in order to clean, replace parts or fill in filter media. Now the pump head and the canister can be taken apart and re-clipped together in a jiffy.
Afterwards the whole filter is clipped into the holder in the aquarium.
