i just need to know if i can use a skimmer for a fresh water tank just to improve water quality?

I don't believe that you'd get much in the way of results with normal freshwater tanks.

Generally it is difficult to generate a small enough bubble size in freshwater to achieve effective foam production (except in cases of very high organic loading) and therefore protein skimming is mainly only recommended for seawater or brackish applications where the salinity is more than 16 ppt. However, a number of freshwater skimmers are available for use in ponds.
