Opinions on UV sterilizer use in breeder setup

The small swimming creatures are far more likely to serve a live food for the fry (and some parents) than they are to be harmful. The UV in that aspect would be harmfull to the system.
 
Many professional breeders use UV on their centralized systems. Sure, you can start with clean broodstcok and quarantine, but if anything manages to get in you're sunk. Then you have to medicate the whole system.
The systems from Aquatic EcoSystems, which are designed for use in maintaining valuable and delicate zebrafish mutants, incorporate UV, as does the system Hoff used in the IOH clownfish breeding facility. It provides a margin of safety.
Disease will happen in a hatchery, and it's best to be prepared for it.
 
The UV sterilizer assures cleaner water, and will help with disease control.
 
So lets assume some disease does get in, UV will cure it 100% every time and you never have to medicate?
In theory, yes. In practice, no. But when something gets in, it is a lot less likely to spread from the initial site of infection, and will allow you to isolate infected tanks before you have to medicate the whole system.
