Air Bubbles in DT

This just started happening today on the right side return pumps. Happening periodically. Looks really cool to me.
Any concerns?

Pics would be great, especially with blue channel off.

Now I’m confused. I added a picture and it’s locked. It won’t even let me look at it.

do you know where it is sucking air from? I think airbubbles, mainly micro can irritate fish gills.

I had micro bubbles actually bloat a naso tang. Stopped the air leak and it went away in a day of 2.

I figured it out. My sump level was low. Didn’t check it for a few days. Now I’m good. Thanks for the replies.
