What kind of plant is this

[Melissajk]

I have a green plant growing in my tank and I'm having a hard time identifying it. Is it alge? Good or bad?

Looks similar to Halimeda but not sure if it is or not

Saltwater Aquarium Plants for Marine Reef Aquariums: Halimeda Plant (Algae)

Thank you, I was reading about Halimeda. It doesn't sound to good. Not to sure.

Halimeda is a good macro algae, if it is that I wouldnt worry about it at all. Macro can absorb some nitrates so its a win win, plus it looks cool, gives the tank some color and texture.

Will it absorb calcium?

looks like something out of the Caulerpa family IMO
grows very fast good in sump not in tank

Halimeda is a calcareous macro algae. It builds its leaf blades using calcium. Grazers won't eat it. It's up to you if you like the look of it or not.

I got rid of it last night. It was soaking up all the calcium in my tank. Eventually I will want coral.
