UV or a Ozone Unit

[Galantra]

Ok i am kinda confused when it comes to this wanted to know what would be better for my tank. I am in debate to have a Ozone unit or just a UV i know they pretty much do the same thing.What will be better in the long run i am looking for that really clear water quality that i think i am lacking. Any help is appreciated

If clarity is what you need,you can't go wrong with either one but the ozone might be for you in my opinion.
