At Least it's on the bottom and you'll most likely never see it right???
Awesome tank!
You're a brave brave man putting more than a ton on your 2nd floor
So I was very worried about that. I actually went out and purchased some jack posts to place in the basement, under the tank. After filling it with tap water and looking at the beams in the basement, they seemed to support the weight with no problem. I'm still planning on reinforcing the beams but I've returned the jack posts. My basement is fully finished and I was trying to avoid putting poles in the middle of the room.
