What is this?

Does anyone know what these white dots are on my glass?

Does it move ? If not it looks like coralline algae.

Are they white? Cause they might be purple under white light and be the coral line algae growing on the back.

They are definitely white. Light is semi white and blue right now. And right now they don’t move I’ll know by tomorrow if they are not in the same spot.
