Yes....but there's a slight health issue with the ozone. Mostly for me, as I'm the one who spends all the time back there breathing it!

Got'ya. that is the main reason I do not run ozone.

Some Parrot deaths and health problems have been connected to ozone generators in the house hold. Having 5 birds in the house means no ozone for me

Wow, neat skimmer cup mod

I was just wondering though, can you really smell the ozone? How much do you dose? I'm just asking as I ran ozone for awhile in small doses (like 25mg/hr) and never smelled it (even when I cranked it which made me wonder if it was even working or if the "tank clarity" was all in my head.

Oh yes, you can certainly smell it. It's not a strong, unpleasant smell....sort of vaguely electrical-like. The ozone generator I have is 250mg/hr. The ozone is controlled by Redox measurement on the AQT controller, but it mostly runs all the time. Redox swings daily in the exact opposite way to pH and temperature...going down in the daylight, and up at night.

As Redox rises at night, the controller shuts off the ozone, so there are periods at night where it is not on. I'm not certain, however, that the 250mg/hr that I'm adding actually has a measurable impact on redox in my tank. I may not be adding enough to be concerned about.

Yes, I don't know if it is really doing any good or not. It seems to be doing no harm so I'm going to continue. Ironically, smelling the ozone is about the only way I can know for sure that the ozonizer is still working!
