Elos Skimmer/Ozone Injection?

I have a new setup using a Elos PS200 Skimmer. I would like to introduce Ozone into it. There is two Nipples on the air intake. Can I use one for Ozone. Is there some place else it should hook up to, or is there no way on the PS200?
If not, can you recommend a Reef Octopus that will work with Ozone. I have a System 70, 55gal setup.
