A very minimal ripple should eliminate the problem.  I have
used this approach with adequate results.  Or, adding one or
two black mollies to your tank *will* eliminate the problem.
One of my LFS will let me buy them and return later.  Two
black mollies cleaned up a recent serious surface scum
problem within a few hours in a 75 gal tank.
