Best way to remove algae from a frag?

[mpatz]

Hi all,
I have a sun coral frag that is getting green algae (dont think it's hair) on its exposed skeleton and the frag tile.
What's the best way to remove it without hurting the coral?
I've heard of using hydrogen peroxide but will that work on non-hair algae?
Thanks
Will post pics soon.

Heres the pic, I did one 50/50 water and 3% peroxide dip about 3 days ago haven't noticed any change. Sun is still opening fine as well.
And yea I know I have random sprigs of red turf.

Hermit crabs. I have 20 of them in my 63 gallon cube. I put a new frag in there and they swarm over it leaving it spotless. They even pick out algae in between zoas.
