Something to consider:
I have a persistent problem with surface scum. I have to run a skimmer constantly on all my tanks. I adjusted the height of the dividers so that they are slightly lower than the water line. That way scum doesn't get trapped on one side of the tank. Of course I could always add a second skimmer.
