People have reported excel killing algae, but seachem doesn't advertise it as an algaecide. You can try that if you wish, but there is no guarentee that it will work. Other ways include scraping them off manually with an algae scraper. You can also perform more often water changes tor remove nutrients (remember to test your source water!) or get more plants. Marimo moss balls are pretty much a form of algae that consumes the same nutrients as algae. I have also seen a thread in the DIY section on an algae filter (check the thread to learn more).
Just a few options out there, there are more out there.
Edit: If it is the algae suspended in the water (blue green algae right?) then the best way to remove it is direct water changes.
