Do some research on the history of skimmers. However the short answer is no they don't work on freshwater tanks thus the reason you don't see them on anyones freshwater tank!

They were originally created for outdoor ponds but it was found they are a lot more effective with saltwater because the surface tension of saltwater is less then that of freshwater allowing for much smaller bubbles to be formed which is essential for the efficiency of the skimmer.
