I use it on my planted tank. I made a couple of threads asking for help/ideas but no one had anything to say.
It was very expensive, had to buy a lot of special stuff, have to stay on top of changing carbon so I don't hurt myself or kill the fish, and I don't know if it's even doing anything at all but using it anyway because I already made the investment. I wouldn't do it over again for freshwater.
It works by oxidizing organics. People use it with skimmers as a reactor but you are not supposed to. You have to be aware of what kind of plastic it's exposed to and you have to filter both the air and water after it exists a reactor (need a reactor, but they are all designed for saltwater except large ones for ponds) You have to use an redox controller to use it safely. Mole for mole it is more toxic than chlorine.
It only exists for a few seconds in the water before oxidizing the organics and breaking down into O2 and oxygen radicals, but once there's little to nothing left to oxidize it will start to oxidize the surfaces of the fish gills. That's why you have to filter it out of the water. It will do the same thing to odors in the air, but it also oxidizes the lining of your lungs and everything else. It's really a PITA.
Fun fact: I was youtubing videos about it and some people do Ozone enemas as some pseudoscientific health practices. Some shoot up with it. Stupid.
