I am considering adding ozone or UV to my tank. Anyone run either? Or both? What’s better?

Depends on the tank. Ozone is great in a coral heavy tank and UV is better for a fish heavy tank. Ozone will help with clarity and toxins from the corals in a big coral tank. UV also helps a lot with clarity but is a bit more geared towards keeping the water pathogen free for things like Ich in a fowlr tank but won't remove toxins. UV is easier and a good place to start if clarity is what you're after. I just only run them when I have to in the reef tanks since it will destroy some beneficial bacteria along with the bad, which hopefully you don't have anyway. I turn the UVs on for a few days once a month or so if I feel like things are looking hazy. Power filter does most of the heavy lifting for clarity.
