UV sterilizers-your thoughts

[rodsboys]

I am expecting a couple of new frogs in a couple of weeks. I currently only have one. I have a small "in tank" UV sterilizer in my fish storage boxes. I have been considering running it in the frog tank, especially when the new frogs get here. What are your thoughts? I assume it can't do anything but help. Should I consider running it all the time? It has a adjustable flow and the design is some what similar to a powerhead . My frog did do some time with it when she was smaller and in with fish in a 60 gallon. She has never shown any signs of disease, but everytime I read about or see some diseased frog it worries me. I try to provide the most sterile environment possible (clean bare bottom tank, well established adaquate filtration, etc.)
