Worms on glass?

I just noticed these tiny little worm looking things on my glass. So small that I couldnt get a good shot of them. Any idea what they are? They are everywhere!
 
They are all gone now. This tank has been kind of a nightmare. I believe this to be cause from too much nutrients in the water. Main cause Im thinking was my fluval I had in there. O well new tank is cycling and no more fluval and more flow. Thanks!
