UV kills dinos and bacteria in the water column.
The dinos are free floating in the dark, but set up farms in the light.
The nitrifying bacteria are predominately not free floating. They're resident in sand beds and inside rock structures.

Every night, the dinos float kills them. The skimmer and nitrifying bacteria export/consume their remains. This strengthens the good bacteria.

I don't see UV as kill or cure with chance determining the outcome. The day/night transition in dino behavior determines the ultimate outcome.
