Owners Manual


Recommended for Aquariums 5 gallons to 30 gallons


Eheim Liberty Power Filters use a very simple and effective design that is perfect for saltwater and freshwater aquarium filtration. Hang On Back (HOB) filters are most commonly used on smaller tanks that cannot have a sump added or temporary tanks like quarantine or hospital tanks. The Liberty filters can be set up in seconds by hanging them onto your tanks vertical wall. HOB filters will also add flow to your tank encouraging gas exchange and helping suspend detritus for removal.


Each Liberty 75 Power Filter includes an activated carbon pad that will trap large particles, along with microscopic particulates and organics. They also use a secondary filter pad that allows passive water contact for nitrifying bacterial growth and encouraging other biological filtration functions.

Note: Eheim Liberty filter systems must be primed before powering on. Fill the filter chamber with aquarium water until it is full.
