UV light is a neat little thing. It can kill a lot of the little nasties that are living in your aquarium, and help eliminate a green water attack. However, I doubt it will have much effect on killing of BBA. It may work on some of the BBA spores that could be floating about the aquarium, but once BBA gets a foothold, I think balance, good CO2 levels, and an SAE is about the only way to attack it.
