Funny thing, I don't remember this thread. Probably because I stopped using O3 a year or so ago. I loved the results but didn't like the hassle of running carbon 24/7. I never thought you could run O3 without carbon. From reading this thread I guess I was wrong. I'm just about done cycling a new tank and think I'll try running low doses for a couple hours a day; of course I still have the equipment. It'd be great to get the benifits without the down falls.
