Objective: How to ozonate your drinking water?

Which of the following solutions is more sound in terms of naive physics reasoning?

Pick your answer from:
(i) Purchase an ozone generator and hook a plastic tube to fit the valve where the ozone is released. Place the other end of the tube into the water container. Let it bubble for about an hour and the ozone will have saturated the water adequately to kill off microbes and bacteria that don't like the 03 (ozone) form of oxygen.
(ii) Take your drinking water jug outside and leave it in a place where it is protected from flying or crawling creatures. After an hour the natural ozone and sunlight will have been absorbed into your water which will have saturated the water adequately to kill off microbes and bacteria that don't like the 03 (ozone) form of oxygen.
