Help with Black beard algae.

[Coryking]

So for a while now I've had black beard algae. It's starting to get quite bad now, I'll attach some photos. It's mainly on my Amazon swords, sagittaria and my hydroponics plants roots. I tried removing it by hand but it just won't come off without me removing the whole leaf/root. Is there any treatment for it or any fish that eat it? Thanks.
