Ozone is indeed blocking UV light from the sun which is a very good thing. But that is naturally occurring ozone in the ionosphere and have little to do with the ozone we experience here on the surface. Ozone is a very strong oxidizer. It tends to react with most things causing it to oxidize. This can be good or bad. It is good because it acts as a disinfectant as it will kill bacteria and virus and also destroy other poisons. But it is bad when it kills humans or fish cells. Because ozone causes damage to humans and animals too and not just unwanted pollutants it is usually not the best way of cleaning the air or water. But it is often more effective at cleaning then other alternatives. Overall some amount of ozone will do more good then harm by cleaning the air but too much ozone will do more harm then good.
