OH, and its on my home made 2x4 stand which probably wighs close to 33-35lbs.
The house is 33ish years old just in case that helps any.

So approx 400lbs of water, plus 250lbs sand, plus 35lbs of stand. That is already an overestimate of weight because the sand will displace some of that water. We will call that a nice even 700lbs, 40 breeder is 36x18 inches or 648 square inches, 700lbs divided by 648 square inches is barely over 1lb per sq inch. I had a 135 gallon old oceanic tank(extra thick glass) on a nonloadbearing wall in a 100yr old+ house at one point. It gave my landlord fits every time he looked at it, but in 5yrs+ I was in the house we never had any issue with it.
