TORI wants to know:
I went to Lowes and bought some pavers and wall pavers for my AC tank. How much can I put in there without it collapsing?
There is apprx 100 lbs of pool filter sand and apprx 200 lbs of rock.

When it comes to gravel in fish tanks it 1 pound per 1 gallon.
Which means your safe with putting up to 100 pounds of gravel or rock in the bottom of the tank, just ensure that it is correctly set up on a correct stand.

I dunno that’s a good question really. I haven’t seen anyone that’s measured a tank’s ability to withstand pressures exerted on it like that. I can say basically, the 100 lbs of sand shouldn’t be that much of an issue, but tacking on another 200 lbs of rock on top of that, might be. It’s the bottom section of glass I’d worry about, not the stand or the sides, but the bottom piece itself is what will be supporting and directly interacting with all that rock and sand.
I don’t honestly know if this would be safe or not, if it were me, I’d scale the rock back a bit if you already have that much sand. Mbuna are basically the only African types that really need rocks anyways. Haps and Peacocks don’t typically dwell that low in the tank to get much benefit from the rocks. You didn’t say what type of Africans you have, but if you’ve stocked up on rocks, I’m assuming that means a Mbuna tank.
