Daniel, If the tank were firmly anchored, I'd worry about the sides bursting due to the pressure of "sloshing" water. If the tank can move, "give" a little, I'd expect there to be less stress on the glass. Just a thought. Hmm. Aquarium air bag (like in automobiles)?? I wonder if there's a market there? :-) Mike Wise Daniel Gottsegen wrote: > If we had a stronger or a longer shake, I don't know how well it would hold.
