Strange Algae ID

[CJBuckeyes]

This long, spiral algae has really taken off in my coral QT tank. It's starting to surround frags a few frags, and grows back quickly. I can't find anything like it on Algae ID threads. Any one have an idea of what it could be?

Not sure, there is a fine caulerpa that looks similar, great tang and fox face food.

Thanks guys, very helpful. I can't believe the growth rate, this is just a few days after I cleaned my frag tank rack.
