Id help dino or cyano or diatoms?

[reefcadet]

Hello, I've searched and googled but honestly all the pictures of these 3 look the same to me and I have no idea what it is now.


New tank, cycle finished two weeks ago. Added two clowns 1 week ago.


These little brown spots showing up on rocks/sand.

The largest spot i swear has air bubbles. I do not know what it is.

Expertise appreciated, apologies for dumb question.

The last picture looks like diatoms and it’s completely normal. It’s a sign of a growing tank consider it page 2 of your long reef journey lol
