Hi all, I am considering putting a 6 ft tank in my living room on the main level of my house, ideally something in the 180-200 gallon range. Together with sump and ATO I'm guessing this would come to something like 260 gallons of water. The basement is directly below this spot and so I'm a little worried that I will overload the floor. As I currently have it planned, the tank would run perpendicular to the joists and would be right next to an exterior wall. The other thing in my favor is that the main floor is ~10 inches longer in that direction than the basement is. I believe this entire 10" is concrete... as such I THINK half of the tank is sitting right on top of concrete or on top of the framing for the finished basement wall. What's the best way to get peace of mind that the floor will be ok? I wouldn't even mind going bigger (we've got the space there) but I'm just unsure of what is reasonable and safe.
