Hair algea

[molybdenumman]

I seem to be having an outbreak of hair algea. It actually looks like moss growing on some of me live rock and corals. Can anyone recommend a method to get rid of it? Is there a cleaning procedure I should employ? Is there a fish that could accomplish the cleanup?

What might be causing my green hair algea? Tank chemistry seems to be alright, so I'm stumped.

Thanks
