Green algae

[AquaticFinatic]

This is most probably a newbie question etc but I'm all outta ideas! I have a green film algae that keeps coming back time after time. I can clean my glass and within about an hour or two it's back again if I leave it for a few hours I can't even see in my tank. I'm cleaning twice a day here. Any advice please fire away. Thanks in advance :biggrin:
