Unknown algae/scum

Can someone help me identify what this on top of the surface of the water in my tank? All was well until about three weeks ago. I noticed salinity was low and I brought it up. Nitrates, alkalinity and phosphate were all fine but the coral are stressed. Even softies aren’t opening. I don’t know what to do. I thought about doing two 50 percent water changes but I don’t know what to try. So far I’ve tried UV and chemiclean as well as dosing brightwell neonitro. It’s almost like dino but doesn’t seem the same consistency. 

Parameters:
1.026 SG
78 degrees Fahrenheit
2 ppm nitrate
7.8 alk

Can you get a picture with more white. It's too difficult  to see with the blue.

 

What are your phos levels at?

 

How old is the tank?

 

What media is used?
