Agree looks like trapped air bubbles. Could be from the algae or if you pump from the sump pulls air through it.
You're just going through the ugly phase. New algae like the one in your picture traps the oxygen it produces from photosynthesis. Once that is gone and the harder calcareous algae takes hold then you really won't see that anymore.
I would up your clean up crew. I am going through the ugly stage myself in the new system and I just added 500 astreas, 100 ceriths, and 50 hermits. They are going to town and the algae is 75% gone now within a week.

I agree they seem diatoms but I could see some red velvet areas on some of the flat rocks (I might be wrong and could be just coralline).
If these are cyano you should see them partially reducing in size when lights are on and easily removable with your fingers (unfortunately this is temporary as they grow back immediately). I would increase the flow, especially in those areas and could try to use hydrogen peroxide. I think it was 30% h2o2 1ml every 10lt but I might be wrong, can someone comment about it?
If these are diatoms, h2o2 will not help, increase flow and cleaning animals. Did you change light or light bulbs recently? Did you increase the light exposure?

Posted some new photos. I earlier posted with all of my info on a different older thread because I lost track of this one. I do not think it is Diatoms (Phosphate is 0.08, which has been constant for more than a month; there are no silicates) or Cyano. Using a turkey baster, the algae comes off of the rock pretty easy. The alkalinity is low at 5.7 so I am raising it. All other parameters are good. I am planning on beefing up my clean-up crew per the earlier suggestion.
