well. for weight.. im perdy shure that the water is the heaviest of everything you will put in the tank.. ( water weigh about 8lbs a gallon.. and in 1 cubic foot area... you can hold about 7.5 gallons of water..) so the rock thing is nothing compared... imo... and as for a tank just exploding ... i had nover sen that personnaly but heav heard it happening when people set there tank and stand crooked ( not lvl) and uneven weight distribution causes the tank to explode..

Actually the rock is heavier than water thats why the rock doesn't float......
As for tanks exploding or breaking from the weight I've never heard of it.

No.. rock is more dense than water. That's why it doesn't float.
I can't imagine you will have a problem unless your tank is not level. Or if there is something under your tank that would keep the bottom from sitting flush.
