I agree, gotta due something with the cup drain.
is there an ozone port already installed?
There is a plug that comes with the skimmer for the cup drain, so you do not have to use that if you don't want to.
There is not an ozone port installed on the skimmer already, however you could easily inject through the venturi if you wanted to.
