We may be moving to a new house and I would have to put my tanks on the first floor. I have always had them in the basement and never needed to worry about weight. If I remember my chemistry correctly, freshwater weighs 8.33 lbs/gal. Salt water is obviously more dense. I am sure someone here has that weight.
I can figure out the weight of the tank, stand, live rock etc.
Is there a rule of thumb as to how much weight is safe to up on a floor? Its a pretty solid house but I have no idea what would be safe.
BTW, the tank is a 65 gallon tank. The stand is MDF so it doesnt weigh too much. 20-30 lbs. maybe.
I also have a 110 and 55 gallon FW tanks. I may need to get down to 1 tank because of weight. We will have to see.
