Maximum weight in glass aquarium

[StarskreamX82]

I found some rocks along the river earlier today for my new aquarium. They're pretty heavy and I'm trying to find out how much a glass aquarium can hold. It's a 29g on a regular stand, so there's no support along the bottom.

I've put some pretty big rocks in some of my tanks with no problem. If it lays fairly flat then it should be okay, but if you are concerned about it causing pressure points then just get a piece of eggcrate (lighting diffuser that goes in ceilings) and cut it to fit, it'll spread the weight more evenly.

Yes, that's exactly what I was worried about! I should have thought of that. Thank you!

I had around 150 lbs of rock in my cichlid tank with egg crate in the bottom. Never had any problems!
