Killed Dinos. Now GHA...

[Dark_Knightt]

I finally got rid of the dreaded dinos, and now I am having a green hair algae infestation in my tank.
Any tips? Other than manual removal? Any good CUC or fish for a 20g? My hermit crabs havent touched it, and its too big for my snails to eat. I had an emerald crab but the clowns killed it when it got to close to their lair.
Pincushion urchin maybe? More crabs? Blenny? Snails?
Thanks a lot!

It’s comes off the rocks really easy. Long bristle kitchen scrub brush and it pretty much wipes off.
