New with Cyanobacteria

Looks like air build up in the algae to me.

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 was thinking it looked like air as well. I have some very long baster style feeders for my tank that will sometimes create air bubbles like that if I don't have it full of liquid when I feed the tank.
