I got a UV sterilizer for my 55 gallon tank, since it was having green water algae problems. Well, the problem went away before I received my UV sterilizer in the mail. Now I am not sure if I want to use it right away or not.

If I use it, does it weaken the fishes immune systems by being accustomed to a nearly sterile environment? If I raise fish in that environment, then move some to my 29 gallon later down the road, are they going to be more susceptable to diseases?
 
This idea of weakened immunity comes up once in a while, but I have never seen any scientific proof. If anyone has proof (not anecdote, not friend-of-a-friend said, not I-read-it-here-on-the-Internet, I want actual evidence) I would appreciate if it was posted here.
