The only time I smelt the ozone was when one of my tubings was pulled out of the skimmer by one of my kids. I later found out online that it wasn't a problem cause the ozone breaks down in milliseconds after hitting the air.
thanks for sharing your experience, i am definitely leaning towards on implementing ozone to my system.
My friend uses the Octopus Ozone reactor, originally he had it hooked to the skimmer but wasn't working well. Definitely has the air dryer as well.
I plan on using a ozone reactor as well.
