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. The adjustable intake depth lets you create the perfect motion throughout the tank to sweep particulates into the filter for removal.


Each Liberty Power Filter includes a filter sponge that will trap detritus and other free floating material from the water column. They also use a secondary filter pad that allows passive water contact for nitrifying bacterial growth and encouraging other biological filtration functions.
