I was wondering if anyone had any solutions to the thin layer of scum that builds up in a planted tank. I think it's a buildup of protein... so would a certain type of fish help in this endeavor? I don't want to disturb the surface with a powerhead because i'll lose massive amounts of CO2. Any ideas?

I have 2 black mollies just for eating that scum. They go crazy for that stuff. Another thing you might want to try is mount a power head upside down with the intake at the surface of the water. It sucks in the muck and chops it up into the water. Alternatively you can connect a tube directly from the power head output and into a hob filter. I used the latter for a while and it litterally cleared the surface in under a minute!
