What is this branch like stuff? What should I do to promote it's growth?

Looks to me like its a kind of branching coraline algae. Not positive though. Do you know what kind of lr it is? I've seen some branching coraline algae on lalo rock before. Anyway, hopefully we'll get some other opinions. Oh, and if it is coraline the best way to promote growth is good calcium and alkalinity imo. Also, mh lights in my experience do not trigger the bloom of coralline that I got with pc.

I do have Lalo Live rock. And thanks for your opinion.

It looks like a dead SPS coral that was originally attached to the rock. Looks like probably on of the thin branched deep water corals. It appears to be bleached and dead so you probably won't be able to get it to grow.
