Is this normal? I had this problem about a month ago but it slowly went away, and now it's back. What are your thoughts?

It's been set for a little over nine months now. I used dry sand from Marco rocks.

I'm no expert but i have 3 theories, It could be Nitrogen gas. It is from anaerobes doing their job and breaking down Nitrates into free Nitrogen gas, I believe it's harmless. It's just doing it's job.
Or... Many forms of algae will create bubbles in the tank. Diatoms, cyano, hair algae at times. Does it look like the bubbles are coming from an algae source?
Then the other issue that was alluded to could be microbubbles coming from your skimmer. These are usually tiny bubbles that are more of a nuisance to you than anything else as they can make the water look kind of cloudy.
If you don't have a skimmer then that theory is out the tank so to speak.

Had the same thing in my tank. I treated like it was brown cyano and now it's gone

Red Slime Algae, it is not algae at all. Reduce your feeding, it is caused by excess nutrients ( Reducing light will do nothing). I can almost promise it will be back. I tried Chemi Clean, it works for a while and then comes back.
It is fairly hard to get rid of.

Just so you know it is a form of Cyano, the bubbles you see are a result of the Cyano producing oxygen as a byproduct of its organic process. I would try a 20% PWC every 4 days or so.

The over feeding has to be the culprit. I've been trying to catch 2 damsels that are causing problems and I have a trap set with food plus I'm feeding every two days regularly. My skimmer does produce micro bubbles but my sump has a bubble trap and I haven't noticed the bubbles in my last chamber. My second guess was and still could be an algae break out because these bubbles are on top of algae. Thanks for the help I'll cut back a little on the feeding.
