Any shock, vibration, etc will knock-off that extra oxygen. This is why most successful O3 systems use a transport mechanism centered around a venturi. The O3 is sucked out of the generator, down a short run of tube, and into the venturi. There is no feedback or monitoring system. These fish are being exposed to O3 which is not optimal.
Reaction needs to be done in a seperate tank.
No controlled means of O3 distruction. No means of input air filtration or drying. Ozone generators need very clean, filtered air to work. Ideally, they also need to have some means of drying the incoming air. Of course, if you enter into this thing with the understanding that you are a guinea pig, then you might find some interesting new tricks with ozone.
