Unhapy Frogspawn

After lights on today, one section of my frogspawn seems unhappy.

There seems to be a bubble in the middle.

Thoughts?

it could be export extra waste from the mouth.... Just a guess

Weird. Could it be from microbubbles? For some reason in this heat I'm seeing some. It could also be from heat, though I was able to keep the tanks below 80.
