So I just did some research and found that one of the mystery algaes I have is Neomeris annulata. Everyone seems to say it is a non-harmful micro algae that will go away. Some like the looks of it. I HATE IT!! So does anyone have some good info on it or has had it at some time? As long as it isn't harming anything I'm not too concerned, it isn't the ugliest thing in the world but not my fav. Any input would be great!!
