Bubbles on rock

[GiannisK]

I have these small clear bubbles just sitting on my rock. My tank is pretty new and it’s recently had a diatom explosion. Any idea what these are? Are they just pockets of oxygen from diatom photosynthesis? Thanks!

Yep looks like oxygen created by photosynthesis!

O2 bubbles from the algae, happens alot in lower-flow areas

There is a method that worked for me, however this is just O2 from bubbles. If you want to be sure, this is what you can do.
First grab 2 jars, then fill one with 1/2 cup of water with the algae that is creating the bubbles, then shake it up for 30 seconds. Then take a coffee filter or paper towel and filter the water through it. Wait about 1-3 hours, out the jar in a bright light area, then if you see small brown strings forming in the water, it is Dino’s. Other types of algae will not reform. I do my see any Dino’s in your tank though.

It's quite common in new tanks.

As long as your nitrates are measurable, they're likely nothing to be concerned about.
