Do diatoms have bubbles?

[charliedarling]

Newbie here… been noticing some bubbles forming on what I believed to be diatoms..? Not sure what I’m looking at or if diatoms typically look like this? Need some experienced eyes to take a look…

Thanks

While diatoms can entrap bubbles, this may be cyano. Best way to I.d is always microscope method.
Assure your nitrates and phosphates are not elevated and tank has adequate flow
