Uv generally isn't needed indoors. It's more for ponds to help clear up the green water some caused by algae. Or in indoor systems on a multi tank sump to help prevent cross contamination.
That isn't to say it doesn't provide benefits still for a single aquarium but its not really worth the cost unless you have a specific problem.
