Newer tank I assume? If it's only a month or so old it's just diatoms and other forms of algae starting to grow onto the sand and rocks.

Microscope is the best way. That way there is no guessing. Very useful tool to have on hand.
I agree unfortunately I don’t have one yet
I’ve had my own issues in the past and always put buying one on the back burner. If I could go back, I would have ordered one before I even got in the hobby lol.

With your lights on for only two months I highly doubt its dinos and its not cyano, cyano is red and dinos normally come with cyano in my experience

I almost want to say they are diatoms. Do you notice any O2 bubbles associated with the algae that disappear once the lights go out?

IMO possibly detritus build up and subsequent micro algae growth. Even the rocks have sand or dusting on them, how is the flow in the tank?
