Can you see the joists below? Do you know which way they run? What size tank are you thinking of putting on the second floor?

I just did a search on this subject the other day, because I have a pool table in a room upstairs that weighs 1000 lbs and I also want to put a tank up there. After reading 100 posts on the subject, my general findings were that if you want piece of mind, ask a structural engineer. 250 - 360 gallons is going to weigh 2000 to 3000 lbs. - that's a lot of live weight for a floor without special reinforcement. Hell, I'm worried about 56 gallons! (Well, there's the pool table also).

I can tell you that when I had my 180, it ran parallel to the floor joists, and was in the middle of a 12 foot span, and only sitting on two joists, so pretty much an un-ideal situation if there ever was one. I ended up adding two LVL beams to the ceiling below, under the tank. Those two beams were sistered to the existing truss joists, and I also added two extra 8,000 lb capacity floor jacks to the wall on one end (the interior one), and 4 2x6s to the wall on the outside, both walls of which had concrete footings because they were load bearing. I was pretty happy with the end result. Money well spent, I think.

I Just moved up to a 125g. I was worried about the weight since It was only going to be on 2 joists the tank is in my dinning room. I cut 9 2x6’s and made them 6’ long then i screwed 3 together to get 3 beams. I wedged all 3 of them between my foundation and used 3 adjustable l.ally columns to hold up the other sides on each beam. I think I could add more weight if needed. It looks pretty sturdy.
