ID this nuisance !

Can someone please help me identify this plant and how to get rid of it... it popped up about 3 months ago when I upgraded from PC lighting to LED lighting... it takes about and hour to clean most of it out but grows back in about 3 weeks... any fish / invert that can eat this stuff?

29gal jbj nano cube with JBJ led pro hood... custom refugium with light schedule opposite display tank lights...
1 clown fish
1 lawnmower blenny
1 bar goby
1 hermit crab
several nassarius snails
small colony of copepods
lots of zoo's, leather corals, kenya trees, mushrooms,

Looks like Caulerpa Racemosa.
Great macroalgae for removing nutrients, but it can be pretty invasive in a display tank.
Best way to remove it is to just keep pulling it out... put it in a refugium connected to your system - and maybe add a tang or other herbivore to your system that will eat the mess out of it.

Definitely C. racemosa, and as you're finding out, it's a fast grower. It and its variants are actually banned in some states as a noxious weed along with C. taxifolia and its variants.
That being said, it's great for nutrient export. Be sure to freeze the clippings for 24 hours prior to disposing of them.
