Hi Web,
I've never heard of a Sander's Ozonator but it may be common in Europe. In general ozone is introduced into the skimmer or a reaction box. After a fixed contact time it is removed by running it through activated carbon. Direct introduction into the tank can cause serious problems and is never allowed.
Dosage is usually around 0.1 mg/l/hr but varies depending on the organic loading on the tank. Almost always a redox (ORP) controller is used to adjust the dosage with a value of +300-+350 mV being a common shutoff point.
I wish I could be of more help but you would be wise to ask on our Lighting, Filtration and Other Equipment or the Reef Discussions Forums about your specific equipment. I'd also go to the manufactures site for a manual. Misuse can do much more harm than good.
