I'm using the shelves mostly for grow out purposes, and for QT as well. I'm now not sure if I am even going to put rock in the display. Maybe I'll just do a small display with eggcrate and then a large sump/fuge with rock.

Let me know how your new tank works out. I am curious about it.

I have to go down into the scary crawl space to look for PVC before I head out to buy some. Did you just use zip ties, or did you use Weldon type prodocuts?

I used a combination of zip ties and underwater putty. The rocks were a little wonky with just the zip ties, so I mashed in some putty here and there to firm things up.

I hope a combo a zip ties, superglue and weldon work. I want these frag racks to turn out well the first time! FYI eggcrate is a PITA to clean up after. I cut my racks a few days ago and I'm STILL finding pieces of white chips.
