green algae on front glass

[mrcopitr]

Hi,

For the past days I had to clean the entire glass of my aquarium on a daily basis from a green algae film. I did clean my front glass this morning of this film and when I got back from work 8 hours later...the glass is already starting to be covered again...Is yhis a normal cycle in a 2 months old reef..I currently have no other algae problem...I've already had the green stuff on my live rock a few weeks ago...that's all cleared up...

please give me your input on this green film...

thank you

Marco
