Micro bubbles when light are on

[Mente Fria]

Can anyone explain me why this is happening with my reef tank.
All parameter are normal, rock is relatively new on tank but never shows this bubbles until i do a water change, before the wc everything goes normal.

bubbles just come out when light are ON...
Read a lot stuff of algae and oxigen but i want to know what can i do to eliminate this,

i use a turkey blast to remove them, but they came back.
TDS METER 0

Diatoms. Oxygen. Specially if the tank is newer.. itll go away over time

Do you see any brown on the rock, coral, or sand bed where the bubbles are? It sounds like it could be dino's being that it only occurs with lights on and after water changes. Can you post a picture with white lights on and no blue.

Before WC everything was normal. This in only happening with the new “stax” , my other stax is bubble free with no issues. Later i post a pic with whites only

It sounds like the water change stripped any nutrients out of the system allowing dino's to settle in. The new rock does not have any microfauna to outcompete the dino's allowing them to colonize there. The existing rock has had time for bacteria and microfauna to keep the dino's in that area at bay.

This is anecdotal based on the limited information. Better pictures and more information about your system will help in diagnosing.

Still leaning towards my original thought. How old is the system? Do you test nitrates and phosphates? What are those levels? How long has the "new" rock been in the tank?
