Protein skimmers work on the basis of surface tension.  Since fresh
water has a much lower surface tension than salt water, a normal protein
skimmer won't work in a normal freshwater aquarium.

I have heard of using foam fractioners to help clear the water on ponds,
but in order to make one work, the specific gravity of the water has to
be pretty high.
