Weight of decor?

[HannahJo]

I don't know why I've been feeling paranoid about this lately (and I've never really researched/asked about it) but how much weight is safe to put in a 72G bowfront aquarium, as far as decor goes? I have some beautiful rocks that I want to put in there but for some reason I'm thinking it will be too much weight and I picture the bottom breaking out....

If you have substrate, the weight will be distributed a bit. 72 gallons of water weighs 576 pounds. I don't think another 40 pounds of rocks will make any difference.

How much weight for rocks in a 72 ?
This is a 10g ;

^^I had maybe 700-800 lbs of rock in that one !^^
