Ozone to clean fresh water tanks

I was wondering if anyone else use O3 to clean their fresh water tanks/lines. After numerous complaints from the DW about our water smelling like chlorine or bleach, I now use a venturi when filling my tank which injects ozone from a small ozone generator. No more smell, and the O3 removes more nasties than chlorine.
We seldom drink from our tank, but we do brush our teeth, clean dishes, and obviously use it for showering.

Steved28, I have been recently researching water treatment for my off grid camp and rain water collection and ozone injection. I like your idea of injecting the ozone as you fill your RV tank. I also believe the active ozone will sanitize the tank and lines to a degree as well, and you are injecting a good amount (several times over the recommended amount for an RV size tank) of ozone into your system, so it should be effective. I plan on installing a liquid gas mixer (LGM) inline downstream from the venturi to insure good mixing in the water and maximize the process. My only question is possible effects to the water heater as it is metal. The ozone removes iron from water, so how will it affect or corrode the metal parts in the water system. I use a So Clean system, which is an ozone injector for my cpap, And it does a wonderful job of disinfecting my medical equipment, so I know the ozone is an effective disinfectant. Maybe the answer is just to not run the recently charged water through the hot water system during the initial period to avoid active ozone in the metal water heater tank.
