I was reading up on that last night. They say they are very
effective on algae, but it of course needs to be in the water. UV
would probably be very good at preventing expansion of the BBA by
killing the spores and gammets traveling in the water. It would
probably kill those outright which in theory would stop the spread of
BBA. But of course it would not do anything for the stuff already on
surfaces in the tank.

UV might be a good way to go for someone who wants to mechanically
get rid of what they can themselves, and then use the UV to kill the
spread through the water.

I'm going with Chlorine. The possibility of getting rid of BBA
permanently is just too attractive to pass up.

Chris.

Good luck, and take pics, document and keep us posted... your endeavors will
save someone from giving up the hobby in years or days to come...
