steve, i run ozone too, and love it. you just have to be VERY careful. residual ozone in the air is very toxic for everyone in the house. they tested that it can shorten your lifespan even with small exposures over time. so you definately need to run carbon after your ozone setup, and also wherever any air can escape.
the good news is our noses are extremely keen to any ozone in the air, so if you can smell it, fix it!
id highly recomend running an ORP controller also, you can easily nuke your tank without one. id shoot for around 375 400 orp.
