We made a little more progress today. We built one set of the tank racks today. I think we beefed it up a little to much, but i know it is not going anywhere. We used 4"x6" as the support post on the main rack and 2"x6" for everything else. The main table will be where the 90 gal. sump, Tiger Shark, and Dart pump will be housed. The upper rack ( not yet completed ) will house the 75 Gal RDSB, 10 gal. Xenia tank , 20 and 30 Gal Refugium's. On the opposite and back wall will be the other tank racks. Here's a few pics.
