I was digging around on an old laptop and found some photos of Hunter Wong's show tank at Lucky Goldfish in Oakland from back in 2010. It was a glass tank with either two or three 400w 20k metal halides and had a huge surge tank above providing a lot of the flow. The rest of the flow was from old Tunze pumps. First time I ever saw a Rhyzotrochus or a Borbonius Anthia as well. I know @Thales will get a kick out of this.
