Guys, i was wondering if anyone can tell me if the floors would hold a 150 gallon aquarium. It’s going to be approximately 2500 lbs.
I'm so concern so i decided to put an extra pressure treated joist across six to seven joist with three jackpost that is suppose to hold up to 9100lbs each -- to provide extra floor support. I am actually going with location A as shown on the website and the "wall bearing" isnt a wall bearing, after stripping the concrete work, I noticed there is a 1 inch gap between the joist and wall.

I’m guessing it is about half that heavy. Its only about 1100 pounds of water, add a few more hundred pounds of tank and fish and I doubt it exceeds 1500 pounds. Shouldn’t take too much to support that. That’s like a big spa tub.

hi jerry, thanks for replying. It’s actually 1 ton and a little more. The stand + canopy + tank = 1000lbs
water is 8.34 and since im not filling the tank all the way up, it's going to be 134 gallons instaed of 150. With 150 lbs of rocks and 200lbs of sand and some fishes, taht would be close. Oh yeah rock and sand will displace the water, so we can probably say 90 gallons.

I was going to say I roughed out better than 2,000 pounds with a tank and base, plus some allowance for rocks/sand. That is a lot of load to be placing on a relatively small area near the middle portion of wood joists.
You should have a structural engineer take a look at that for you, including load sharing/increases between the members based on deflection compatibility (it's not just straight addition of the loads) and how the jack posts will be attached/supported. It will be money well spent ... the last thing you want is that huge tank in the room below because you didn't consider something or size/attach things correctly.
It's pretty straight forward for a good engineer, but I dont travel that far ...  ... Maybe one of the guys here from your area could refer you to a good local engineer for small residential projects like that.
