I decided to go the LFS and study their SPS tank. It was quite nice and I decided that this time around I would do mostly SPS, tangs and then we'll see.
I checked out their flow strategy, read a bunch from the Reef Central posts and determined I needed a new sump, return pump, reactor pump, chiller and chiller pump, ph probes and lighting.
Mike and Justin from the LFS are a great source of knowledge. Plus, they are really nice and helpful.
My parallel conquest was to design a sump. I wanted a 72"x24"x20" sump that had bubble chambers to catch all of the bubbles. I also wanted a filter sock area, a live rock section, an in tank skimmer (reused), a built in deep sand bed refugium and a return section. After some help from Mike and Justin on some fine tuning, it was time for an acrylic manufacturer in town to build this beast.
