Review on 🐠 AQQA Aquariums Power Filter, 2W 80GPH External Hang On Fish Tank Sponge Filter with Surface Skimmer, Adjustable Flowrate, 3-Step Filtration Cascade for Freshwater and Saltwater Fish Tank by Rodney Sample

This pump was a real disappointment. I bought it because I wanted the surface skimmer to be mostly outside of the tank and this HOB seemed to fill that need. As a surface skimmer, however, it didn't work at all. A piece that floats is either floating too high or too low, in any case it is not pulling any water from the surface at all. just as loud as many others I've tried. Basically that's the only reason it gets two stars. If you're just looking for a HOB filter, it's not as terrible as others I've tried.
