Black hair algae issue

Hi! I’m looking for a chemical treatment for black hair2black beard algae. I’ve been trying to fight it off manually and with peroxide and it’s not going away. I have a 55gal with shrimp, oto’s, and tetras. Everything I’ve read (algae fix, excel, etc) states to not use on invertebrates or remove them. Removing them is not an option. Any thoughts from the community? Thanks in advance
