I've heard several people say that the long thin hair algae (Spirogyra? Zygnema?) doesn't like salt, and that you can add the right amount of salt that will stop it from growing but not bother the other plants. But you never know how that's going to work in reality. The biological additves are often recommended under the assumption that better biological filtration can take away the nurients that the algae need. I have a big gob of some tall grass-like plant in my pond that seems to compete well with the algae.
