round green spots algae?

[PufferGuy]

So in the past week ive gotten a small cyano bloom, so i changed some water yesterday and im gonna change some more tomorrow. Aside from the cyano, theres these dark green spots all over all the shells and rocks and glass. The ones on the glass get scraped off easily with my mag float but i just dont know what they are... or if they are a sign of something. Anyone have any ideas?? Ill try to get some pics in a little bit.

If it comes off easy,then its probably just regular ole algae.
If its hard,then it could be green coraline.

green coraline?? does that turn pink at some point or stay green?? i dont want all my rocks looking green all the time...

It will usually turn purple (pink) over time.

Green coralline isn't so bad. Combos of two or three colors look cool.
