Hey can anyone identify what this is white stuff is on my glass it’s in a couple of different spots in my tank as well. Also does anyone know what type of algae this green slimy stuff is I have been battling with gha for a while and I am finally on the back end of getting rid of it all with a CUC and also used flux rx about a week a go. Thanks in advance for any help.
