Macro algae

[Wilson]

Anybody know what kind of algae this is?

The stringy one is chaetomorpha. The one with the grape cluster texture is caulerpa.

I agree with @NikkiT. Be careful of caulerpa because it can go sexual and poison your tank water

 

[Wilson]

It looks like caulerpa?

There are different Caulerpas....Caulerpa Cupressoides, Caulerpa Fern Tree, Caulerpa Prolifera, Caulerpa Sertularioides (which is what you have a photo of from Reefs.com), Caulerpa Mexiciana, and Caulerpa Racemosa which looks like the one mixed in with the chaetomorpha in your original photo.

Thank you. I'll probably try to rinse and remove whatever I can and keep just the chaeto.
