With EHEIM LiBERTY you have an uncomplicated hang-on filter, which you can use anywhere immediately.
LiBERTY is simply hanged on the top of the aquarium glass. With its adjustable inlet pipe, you determine its depth into the water and therefore the flow rate in the aquarium. The filtered water flows silently over water slides back into the tank. Thus perfect water circulation is created. The pump output can be easily regulated via the red control knob.
