I have the same one.
This is where I got mine from. That generator should be perfect for your size tank. If your going to use the dryer and the controller, then the BRS package looks like a pretty good deal. I would suggest getting yourself a coralife luft air pump for feed the ozone generator.
Also, you need to make sure that your skimmers effluent is running through carbon and make sure that any vent holes in the collection cup lid are routed through carbon as well. If you dont, you will get a strong smell of ozone in the air around your equipment and anything that is not ozone safe in the vicinity will get damaged overtime.
I use lignite carbon to remove residual ozone from my effluent. I went with a Avast Ozone reactor instead of running it through my skimmer as it was much easier to filter through carbon using an ozone reactor than with my skimmer. Also, my skimmer has several holes in the lid and a self cleaning head which would have been a real challenge to get the air coming out of the skimmer cup adequetly filtered.
Here is a shot of my ozone reactor and my cabon reactor that removes the excess ozone from the effluent. I have about a gallon of lignite carbon that filters out the excess ozone from my effluent. This setup works great!
