Layer of Film, Scum

[ReefSparky]

http://i227.photobucket.com/albums/dd46/lbmcse/DSCF0711.jpgI've had this layer of scum before. Last time the duration was about 6 days. It went away on its own. This time it's been over 10 days, and shows no signs of abatement. From what I've read, it's not uncommon, but it's unsightly. My protein skimmer is working as it usually does, with the main chamber being chock-full of bubbles.

My overflow boxes in the tank receive this film, but it doesn't make it into the UTubes; so it seems to stay on the surface. http://i227.photobucket.com/albums/dd46/lbmcse/DSCF0714.jpg

Does anyone know how to rid a tank of this? Is there a quick certain method, or is it a "wait it out" sort of issue?
Happy Holidays, all!!!

try pointing a PH or your return towards the surface and that should help to get rid of it

i get that film too just at where the flow isn't so good at the surface,like in the middle of the tank surface....im gonna get another powerhead and point it there.

Looks like the return line pointed parallel with the surface clears it up. Thanks for the responses everyone.
