Algae ID

Can anyone tell me what type of algae this is? Not asking about the bubble algae but the long stringy one.

Algae isn't my strong point, but it looks like a Caulerpa sp. to me, possibly C. racemosa or C. chemnitzia (A.K.A. C. peltata).

I agree with above. I think chemnitzia. I have a bunch of it. Good nutrient exporter, but you will need to trim it back from time to time. See my build thread post #61.
