Decided not to use it on my new system, so it's just sitting around collecting dust.
Basically comes with the ozone unit and air dryer. I used it for about 3 months.
Good for tanks up to 200 gallons.
Simply hook it up inline to your skimmer with an air pump and you're ready to go.

Asking $150 for the unit, and I will throw in a small hagen air-pump to get you started.
