Good question Alan,

The use of eggcrate is ok but as the Capt points out you end up having little pockets of sand in each crate chamber. Dowel material is solid and avoids these tiny pockets. Sand shifters can move freely around the dowel material. True, so can some burrowing fish but the dowels form a solid base structure and there is little chance that they will move.

You don't glue anything. Just cut the dowels to the same length and place them in the tank bottom and fill the sand around them slightly higher, about an eight of an inch or less, than the top of the dowels. Once you have a foundation you merely place the LR on top of the dowels.
