Hello! What could this green algae on the glass be? I know the little purple guy is coraline. I just finished battling Dino and in my process I dosed nitrate and pho. Also didn’t clean the glass for several weeks. Is this good or bad stuff, the sides and more top of the glass also have a green film everyday that I clean off and it almost “powders” off. I would say diatoms but it’s green in hue. Thanks for any help!
