Algae ID

[fishyreef13]

Could someone please id what type of algae I’m dealing with. It comes back within a day of blowing it off. Corals do not look very happy. I was away for about a week and came back to this. Thinking it may be a type of dino. I had a lot of hair algae grow and thinking that bottomed out my nutrients before I started feeding again.

Salinity- 1.026
Temp- 77.5
Nitrate- 10
Phosphate- 0.05
Alk-7.8
Calcium- 450
