You should use a skimmer but not a actual "Protein skimmer" for SW
tanks the surface skimmer by Eheim.

Have a look under products/acessories he

www.eheim.com

AFAIK, a protein layer in a freshwater tank is essentially harmless, so
you could ignore it, or drop a paper towel on the surface and quickly
pull it out if it bothers you. I noticed the new Fluvals now include a
skimmer as well. I haven't had a chance to test one out yet.
