Possible Skimming Question?

[Cadbury]

I have a 33 Gallon established Reef, mostly with Zoo's Palys and Mushrooms. I have 4 small fish and the tank is doing great! I'm presently running a mud system and very pleased with it, however there is a film on top of the water that covers probably half the aquarium? Trying to figure out what to do about it, I do weekly water changes....Just looking for some advice?

Thanks....

Do you run a fuge or anything? Might want to look into a surface skimmer on the fuge intake, but if everything looks healthy I wouldn't be too concerned. :)

I point a power head toward the surface of the water to agitate it.

I am running a 10 gallon mud system, everything looks and is growing great! Its just that oil looking crap on a portion of the top bugs me! Maybe I'll add another powerheard to still things up at the top? Thanks for the suggestions guys....
