Hi all, not my picture but it shows what I mean. Occasionally I will get this type of algae on the back glass which after a while slowly vanishes. Is it because the snails and fish eat it? Is this an indication of sth going well in the tank or the opposite?
Finally how does it always grow in so evenly a few Inches below the water surface?
