UV sterilization will deal with any type of algae so long as you can manage to get it free-floating into the water column. It must be able to pick it up out of the water to get it into it's UV light process to zap it. It cannot remove it from plants, glass, decor, etc. - stands to reason, doesn't it ?
For example, it will deal with green dust algae, IF you scrape it off the glass, get it free-floating, thus allowing the sterilizer to pick it up & deal with it. Same with green dot algae & black-beard algae, if you scrape it off and get it into the water column.
Simplistic ? Yes
