TheBigBadReefer,
I think Jake was referring to having a rack of tanks and what would they be made from, i.e. concrete blocks, 2X4's, fiberglass angle, etc. Something similar to what nitrofish has above in his picture.
Have you thought about what you are going to have in your fishroom? For example long shallow frag tanks, a phyto, rotifer and brine shrimp culture station, a sink, floor drain, plumbed air manifold, microscope station, food preparation station, etc.? These are some of my thoughts (wishes) for a fishroom. There is a thread on RC about a guy in Jacksonville, FL and he completely outlines his entire set-up, including his fishroom. Do a search for 180 diamante glass tank (I think), he has a lot of great ideas for a sump, and equipment room for his primary viewing tank.
Hope that this helps. Good luck.
