Live rock on eggcrate, sand or on bottom?

I highly doubt it's possible in reefing. You either have manageable sized rocks in a smaller thinner-bottomed tank or you have massive boulders with a 19mm bottom or thicker. I can't see it happening and the risk at the very worst can't be great.

I did drop a rock and blow the bottom of my frontosa tank out back in the day though. They were juvies and the tank was only a 45 gallon. Difference being I was using heavy rundle rock slabs. Our rock is WAY lighter you're right.

So yeah rock right on glass. I'd consider pegs of some sort if they're short to elevate the rock but I'd never do it with eggcrate.
