A UV does not help anything nutrient wise. It only kills phyto and microbes, causing them to put nutrients back into the water. The water will be un-naturally clear, if that's the way you are wanting it, but corals will get less microbe animals to eat. You might try it without the UV to start, since you can always turn it on later.
