If even one grain of sand gets between the LR and the glass bottom it can focus all the weight above onto that one spot.
Not worth the risk IMO.
Here's a quick calculator...
$10 for eggcrate or oyster shells (in my case) divided by cost of broken tank, loss of all inhabitants...fish, corals, LR, damage to house, floors and hassle of clean up.

So what happens if one grain of sand gets between the egg crate or oyster shell and glass?
