I have tried ozoniser in my pond before. The working principle of the ozoniser I've tried is the same as the ioniser we used for our rooms/cars; basically pumps out air with ozone (O3) and introduce them into the pond via an airstone. As I do not know what is a approriate level of O3 to introduce and neither do I know how to measure O3 level in the pond, I chose a much lower O3 output rating recommended for my pond size just to be safe.
It is difficult to tell how effective or efficient the ozoniser was when I was using it but pond water remain very clear throughout and there were no disease outbreak or skin problem even though I have zero salt content in my pond because I use zeolite in the filter (Pse note that am by no mean advocating zero salt environment cause it can be disastrous if there's a nitrite spike). Then again, my water had been clear and there were no problem with the fishes prior to using the ozoniser.
