Ozone
 

I just purchased a Red Sea ozone generator, orp probe and controller. With in the three hours it's been running, I find my water is already changing. I had a film on the top of the water in my refugium and now it's gone(I use herbie style overflows so no bubbles to keep the top of the water well agitated). I don't know a lot about this system but I have done some research. I would really appreciate it if anyone who has had, or does have an ozone generator sharing their experiance and knowledge/opinions.
