ID on Algae please?
 

I guess when I think about it, I don't have as bad of an algae issue as I thought, no GHA, or turf or really anything, my front and 1 side glass get that typical light film I can just magnet off, my back and other side are almost solid coralline, no green there.
I do have my fair share of bubble algae (Their quite fun to bounce) that just roll around here and there, really not that bad, and whatever this is. Seems to grow quite long if I let it. If spots don't get light it goes white, its fairly hard and crunchy feeling (calcium based?), and I've looked at numerous different sites and all the examples they show are different.
So wondering what this is? And if there's anything that may enjoy a meal of it?

Halimeda algae.

haha all right well I see why I didn't notice on other sites, but with a name now and a quick google it makes sense, thanks!
... But people actually buy this stuff? :neutral: I would never purposely put this in my aquarium, and then there's liveaquaria selling it for $15, shesh. I want it gone, it's ugly...
