Is this and hard, it reaxk easily but remain attached on the rocks
you should prep for war but continue on path until war is needed.
war prep for invasive macros- have a test rock modeled and ready don't go in blindly. we don't have to experiment with the whole tank
pull out one test rock without much on it other than the growth, hold over sink, and pour peroxide from a new 3% bottle across it and the target, avoiding any corals that may be in place. six worms might die/not a big deal, your war is not against worms. let it sit for a couple mins in the air, don't insult the algae past that we're testing its minimum death phase and regrowth charts before you ever have to upscale it tankwide. after a few mins cook, simply rinse the rock in clean sw and put back, the algae will look normal for about two days then we begin charting, off one tiny rock.
we have beaten many an invader in this way.

If it's hard and breaks, then it's a calcerous algae and with the shape of the leaves I'm back to suggesting that it's a type of Halimeda, or a close relative. Folks generally can't keep this alive even when they want to, so I wouldn't panic....I believe it's a fast-grower, so requires consistently available nutrients. Even if you see that it's growing, I'd hold off of concern until you get a better ID.
The other options I'm aware of that look like that even a little aren't hard, they're soft and slimy.
Did you see this yet? http://www.reefkeeping.com/issues/2004-04/nftt/index.php Lots of kinds of Halimeda.
Holler if you still think it's something else......and if so, have you looked for more pics on here or google for anything else that looks more like what you have?

I'm sure is flabellium petiolata, can you suggest me something?
Do you mean Udotea petiolata? I suppose that is a possibility, though it looks like a Halimeda to me as well. Petiolata is a coldwater species. Udotea flabellium gets around 12".
Either way, my suggestion would be to enjoy it. Trim it occasionally for nutrient export.
