My 1700 gallon tank is on the main floor of my house. I placed the tank on a concrete slab which was reinforced with 100 plus tons of sand. It's the only part of the house that doesn't have a basement beneath it. The tank weighs approximately 14 tons, with water, rock etc. Structurally it's built the same as if it was in a basement but it's actually in the living room/ kitchen and faces the dining room.
