While this is just my experience, I use a 25w UV in my 110g planted tank
that has among other inhabitants, 4 discus who breed like rabbits or
maybe a better analogy is "like guppies", and they are very healthy.

I do not see any impact on the fertilizer I use (PMDD). I have seen
reports that UV will breakdown some of the fertilizer components and
render them useless. I ran this tank for a number of years before the
discus were added 3 years ago without UV and my doseage rate for PMDD
has not changed. I've not noticed any difference in plant growth rate.
