what should I get ozone or UV?

I have been wanting something to clarify the water for a while.

I been reading the pros and cons and I am still on the fence. I really would like to get an ozone generator but the fact that the effluent and the air have to be run through carbon to keep it safe is kind of scary if I ever forget to change it.

Uv sounds so much simpler and less maintenance but does it performs as well?


I want to hear form people that are running each of them and how happy they are with it!

I used to run a UV. I couldn't see a difference in my tank.
I've been using Ozone for a little while now. I won't run a tank without one now.
I run mine threw my skimmer. Don't need to use carbon. I have a venturi and recirculating skimmer which breaks down the atoms before they return to my sump. Water is Crystal Clear. I have to downgrade my lighting because of this. My glass only has to be cleaned every few weeks. I bought an expensive skimmer before this, which was a waste of money after using ozone.
 
does anyone else run ozone without carbon?
Also is there such a thing as an ozone reactor I tried to find one but no luck

A Quote from Bob Fenner on Wetwebmedia about carbon and ozone.

Activated carbon/ ozone
Bob,
Is it essential when running ozone, that the returning water from the skimmer be run under carbon???? This seems like a controversial subject. Thanks again. Lee
<Not essential in almost all cases... part of an ongoing "urban myth" in the hobby (along with the lack of necessity of thermal acclimation, floating livestock polyethylene bags... please stop me). There is so little O3 produced by corona discharge hobby units there is exceedingly small likelihood of ozone "poisoning" (and extremely tiny chance of "space poisoning" the area around the aquarium/s it's used in...). If curious, get/use a conductivity or Redox meter and measure the change in water quality in/about the use of this ozone-generating device. Bob Fenner>

I have been running ozone 24/7 for about 35 years in the skimmer in the same tank with no carbon. There is no ozone smell and I am quite sure all of the ozone is being used up in the skimmer.
I have used UV in the past and find it very useful in a goldfish pond but useless in a tank
