All types of boxes will make claims based on common lore to sell it's contents. The effects of typical UV use won't kill your clams, won't wither filter feeders, and won't make your in-laws move out.
What I'm saying is that specific organisms are effected by UV and some aren't.
If UV eliminated reckless algae in the home aquarium, everybody and their cousin's sister would be running it and the well of "help, hair algae" threads would dry up.
Hate to burst your bubble(algae) but this one is a no-brainer.
