Hi Mark
:thumbsup:Nice setup, I also have the same tank as your. I set my up about a year ago. If I have to do it over, I would make a glass overflow box to cover the plastic one that came with the OC 120. After a year, the plastic over box covered with purple algae which is a pain to remove and make your back ground look ugly in the middle of the tank . however, it will not stick to glass or can be scrape off with ease.
as for the light, I run 6x ATI T5 plus 2x 48" Reefbright LED ( for the simmering effect that T5 lacks).
Tek is also a nice alternative or Ice cap T5.
Question, what size is the silencer drain pipe that you got from PA? Thinking about doing the same thing.
Thank you
