What is it and how to kill it?

So what ever this is seems to be bothering my zoa now. Looking to see what it is and best course of action to remove. I have dosed vibrant twice about a week ago for a massive green hair algae which is now morphed into a cyano/Dino issue...At this point I just want to kill this piece lol.

Appears to be algae. Remove manually outside of tank.

That looks like bryopsis to me. Reef flux rx works to kill it . Hopefully you'll get some more eyes on it to confirm.

caulerpa. Throw the plug with the zoas all away. You can try to salvage some of the zoas but I would surgically remove them from the plug if I wanted to keep them.

I think you were right. Once the frag was pulled and I was able to manually pull some of it off it looked alot like bryopsis. I found a post from like 2004 or 2006 about just dunking the whole frag in some hydrogen peroxide for 30 sec. Long story short that's all it took. Thanks for help!
