Live rock on eggcrate, sand or on bottom?

I've used large diameter ABS pipe cut into various sized sections to support some of my LR. Holes in the sides will allow some movement & help mitigate stagnation in the sand bed. If I were to re scape, I would do similar, but instead of rounds with holes, I'd open the circles up into half or 3/4 sections. I'd also silicone them to the bottom, since keeping them in place was a pain while trying to place the rock on them. I didn't know ABS has a tendency to float. Not an issue in your case since you'll be working with a dry tank.

Something like this, but clean up the edges of course:



Not sure I'm a fan of the eggrate scenario, since the latticework would seem to have the tendency to restrict flow & sand movement within the individual squares?

also if you are using dry rock for you aquascape, I saw a video on youtube of someone using a hack saw to cut flat spots onto the rocks where they would sit on the glass, I think that makes things a bit more stable

I use the bottom halves of oyster shells as a barrier between the rock and the glass. That way if a sand sifting critter uncovers them they still look natural
