Is a UV light of any value when it comes to controlling algae in a freshwater aquarium?

Only free floating algal species, such as those that cause green water.
please correct me if im wrong
but wouldnt a uv sterilizer kill other algae spores
or gsa that was razored off glass and being drawn in sterilizer instead of reproducing
Of course. Any free floating spores/algae that has been scraped off that makes it way though the UV sterilizer will likely be killed as well, but that is more incidental.
