Cloudy Buildup on Glass

[jeremye83work]

Hey guys, tanks doing great. All of my new corals ive gotten are flourishing. However, now that i have all these wonderful colors in my tank, somethings been bothering me.
I have this cloudy sort of build up on the front to panes of glass that disrupts ur view. If i lean around the side its as clear as can be. I cant scrape it off and it is most certainly on the inside of the glass. Any ideas what I can do without hurting the stuff in my tank?

Do you have a magnet cleaner???...They work pretty good.

i cant scrape it off with anything including a razorblade. it does not come off like the algae does. it is a film on the inside of the glass.
