Pg_rider,
That is one BEAUTIFUL piece of equipment! 8-)
Given the lack of a waterfall, my Bahia only has the circ pump/ozonator return line. Wouldn't be surprised if the Optima's return line from the circ pump "splits" between the two outlets before ozone is injected into the one.
Just looking at that picture makes me want to go hop in the tub! Surely half an hour away from work could be justified in the middle of the afternoon? I'm getting.... um... carpal tunnel symptoms. :-? Better go "therapize".
