All of a sudden these bubbles are appearing allover my tank. What are they and what is causing them?

I think that's the start of bubble algae I think I had a alot of them then after I had green bubble algae.
I would siphon them out

It is only on the tank’s wall and on the glass. There is nothing on the rocks.

That is how mine started.
Now I have NO idea if I am right or not. But instead of swishing them around I wish I would of just sucked them out. Like I said I have no idea if I am right

Might be oxygen bubbles and that means a photosynthesizing biofilm.

Cyano, bubble, dinos... All the start of something bad. Start by testing your phosphate and nitrates. Let us know your parameters.
Suck that out...

Suck that out...

Good advice lol

How do I eliminate them?

I decided to turn off the thank's lights and do a semi blackout for a few days and see what happens. I am not going to a full blackout scenario where I cover the sides of the glass and prevent all light from entering.
