coderabit21 and Sparky0028,
Both of you could run ozone in your skimmers no problem. Just put a T into your airline going into the skimmer and attach the ozone to it. I actually just feed the ozone right into the venturi inlet without a T. But I assist the airflow with an airpump, because I felt the ozone unit restricted the pull of air into the venturi. But it's a small pump.
All ozone units require either an air pump to push the air through or a venturi to pull the air in. The ozone unit itself does not create airflow. It merely converts the air going through it to ozone.
Hey Zoom,
I'm not sure if you can route the exit water through carbon. But if the goal is to run only a little ozone for a few hours to help clear the water, I don't think carbon is necessary. Ozone is dangerous stuff, no doubt. And a tiny little amount goes a long way. If you used the little skimmer pictured above for ozone and ran it at 10mg/hr on, say, a 100g tank, I don't think carbon is needed.
If you want to run a lot more ozone, then I would suggest placing the above skimmer in a little box that routes the water through some carbon.
