When I put the brown film under the microscope I saw 99% diatoms and 1% dinos. After I turned off the UV, skimmer and carbon for a couple weeks the green algae appeared and quickly took over from the brown film, when I put the green under the scope I see only algae and no dinos. I my case I believe the dinos were out competing the micro algae and when physically beaten back the diatoms took there place, by letting the water dirty up it allowed the micro algae and other micro fauna to get reestablished and out compete the diatoms and dinos.
I didn't restart the UV for fear of decimating the micro fauna again.
Like karimwassef says, you either go dirty or go clean and heavy UV, dirty is working for me.
