What kind of algae is this? pic

[BChen7106]

Hey all,

 

Noticed this hairy thin algae growing on my sandbed and on some of the rocks. At first, I thought it was green hair algae, but when I google pics of hair algae, it seems much thicker and bushier. This stuff is really really thin, but grows super fast.

 

Wondering if this is some sort of cyano. I've had red cyano in the past, but this was different. The cyano I had in the past grew in sheets.

 

Sorry about the quality of the pics, but it's hard to capture.
