Large tank with Pier and Beam construction


New member
I am moving to a new house that is pier and beam construction. I have my 300 for sale as it has a small foot print for a large tank, just 14sf. I am eyeing tanks in the 175-200gallon range. Maybe something 60X36X18 that would spread the weight around. Does anyone have a tank this size on a pier and beam foundation or upstairs? I know this tank is going to be 1600lb plus but when you spread out the weight it isn't any more per sf than 75 gallon tank.

Thoughts, suggestions.

I am seeking out a structural engineer, my mind is just running through options right now.
