Take your time with corals, you have some already and until you get experience it is better to take it slow. Eventually things like zoas and palys will be nice. Would personally stick with what you have fish wise...but if you really want to add one more fish I would say a goby or other low dwelling type fish.
The PH is on the right side and yeah that is the overflow where the protein skimmer is, which flows over and then down across filter media then to return pump in chamber 1. You think put the PH right under the outlet where the return pump flows?
