Blackbeard algae?

I just have a question about this type of algae. Now I don't have a freshwater tank but a friend of mine does and he mentioned that after adding real plants to his tank that he started getting this black algae. I realize that saltwater and freshwater are different and I mentioned that I used phosban to rid my tank of algae. Now I am not even sure if you can use that in a freshwater tank, and wouldn't he need some phosphates for the live plants? Any suggestions that I could pass along to him would be greatly appreciated.

 

Lowering the phosphates and nitrates is good. Have him pluck off what he can or trim the leaves. Siamese algae eaters are the only fish that eat it with any consistency. Flying Fox do not work.

I have had same issues earlier with my anubias and i got rid of them just by introducing 2 SAEs and the Beard algae is Bye-Bye
