I had some goldfish in a 20g. Surface tension film on water.
Put a Skilter 250 on it. It worked. Protein skimmers will
work on FW if there's enough stuff in the water for them to skim.

Some people have been asking about freshwater protein skimmers lately.
Well, I tried an experiment in my unfiltered pea-soup goldfish tank.
Although I did have 1 tsp/gal of salt in there before, I changed 90%
of the water last week so very little salt is left. It's still pea-
soup though. I took a 1.5" diameter ABS pipe and stuck a Y on the top
with the side branch facing down. This gizmo went into the tank and
an airstone fed by a Dynamaster II went in the bottom. Great gouts
of stinking green came spewing out of the top! I was transfixed
by the smell. It smelled exactly like the nitrification ponds at a
sewage plant I was poking around at last summer (don't ask :-) So
you see, they do work in freshwater. Maybe it just depends on how
dirty your water is. Now I just have to figure out a way to catch
the foam and do something with it before it slides back into the tank...
P.S. Here's a picture if you want to try it:
