Just as simple as the title says really...

Acans... not sure the common name or if they have one, but I have some similar ones. Also that's a lot of cyano, do you have a lot of phosphates?
 
Cyno, where? I thought that dark green stuff was a type of hair algae?

Just tested phosphates: between 0.5-1

My bad, not cyano - didn't look closely enough. That also doesn't look like gha, which has much finer filaments. This site has a good guide to common macros: http://www.reefcleaners.org/nuisance-algae-id-guide

Also 0.5-1 is quite high for phosphates in a reef tank - 0.01-0.03 is normal. Doesn't really hurt anything but can can fuel tons of algae (which can starve corals.) Cutting down feeding and some extra water changes should help.
