Algae in my tank

[gclackum]

I’m working on my 2nd month after switching from MH to LEDs. Tank has been up over two years. Lost a few corals on the switch but most survived and they seem to be loving life.
I’ve developed a little hair algae bloom nothing major. And I’ve noticed another algae (see pic).
It appears to be leafs. Any one know what it is and what eats it?
