Have you checked your water parameters? I'll bet your pH and ALK is all sorts of fuzzed up. Some one else can help you with fixing that, because I suck at it . I had your exact problem and the way I fixed it was to stop adding any livestock and put a refugium on it. A refugium is just a bio filter with loads of green macroalgae and red macroalgae. I found that the refugium cleared up my algae problems in a month or so. The green stuff in the fuge uses all of the nutrients and components that your film algae needs, so eventually it starves it out. I'm pretty sure that the reddish brown algae you see is red microalgae, and a piece of red macro will fix that too.

goodluck!
