Will a UV kill off your pods? I have a large pod population and I I currently run a UV. I unplugged it tonight. Will I have a increase in population or will it not make a difference?
 
Everything I can find makes UV sterilizer out to be only effective against micro-organisms. While it would kill natural plankton in your tank, the vast majority of amphipods, copepods, and other macro life are surface dwellers (crusing over the liverock, through the substrate, etc.) and would not likely be that affected.
 
In a tank your size I would not worry about the UV light killing pods. Yes it could kill what flows through the light. You impeller on your return pump will also kill some.. If you had a 30 gal tank then maybe I would worry, but on yours IMO not a issue...
 
that is why I recommend either having your refugium on a different return line than your UV or having an HOB fuge
