I have a story hope it helps
148 gal custom oceanic brick 29" tall x 60" x 18"
Bosses daughter refuses to let him keep it on a aquarium stand wants a piece of furniture from wittings
I tell them it has to hold 2K pounds, and when it comes in does not look like it will but who am I to judge.
Fill up with water and liverock when we hear a crack along with two more.
We pump the water out and remove the rock and thank God no leak.
After the tank is drained the left side of the stand is lower than the tank by 1/2"
Needless to say they built a stronger piece of furniture the second time.
Anyway the tank is around ten years old now and no issues.
