i'm a litte worried

[reefman]

if you bounce by the tank does the water move?

no the floor is solid just gonna jack it up slowly

 

[cassharper]

do it in the middle of a 50% w/c

That will alleviate a lot of the stress from the water movement.

you should empty it out, never try to correct a sagging floor with the weight already in place, just get some rubbermaids and empty 50% of it out into the bins then empty the rest out into the drain ext. Then once just the tank/stand are in place, then put the 2 jackposts and 4x4-4x6-4x8 w/e I used a 6x8 board bolted to my jack posts and put it in place, snuggly crank it tight and then fill your tank back up, slowly every week raise it little by little.

What do you suggest doing with the fish that are in the tank during the process of raising it? Why is having weight on the floor different than not having any if the weight is just going to be back in the same place again?

I just had to do this to my floor and read on the contracting website that you dont want the load in place.Took my about 10 min to get my jack posts in place and cranked up so he could put them in rubbermaids for 20 min? just get the large ones.

Sorry double post but here.

. So you go into the basement and nail another 2 x 10 right alongside the existing 2 x 10 joist. (see:http://www.hammerzone.com/archives/framecarp/supplement/floor/joist1/sister.htm ) Unfortunately this doesn't accomplish much since the load was already in the existing 2 x 10 and you haven't removed any stress out of the existing 2 x 10 by adding another joist. If you had added the new 2 x 10 first, and then put the aquarium on the floor, then the joists would have deflected together and shared more of the load. Same idea with a post. You should either add the post first (before you fill the aquarium with water) and shim it very tight to the underside of the joists, or you should jack upward so that the post carries more load. (see: http://www.hammerzone.com/archives/framecarp/supplement/floor/joist1/raising.htm )

Gotcha. 20 minutes was not my idea of slow. Also if you're going to crank it up week by week, again, what's the difference?

My only concern would be that the stand may have shifted with the floor.

 

[Bud_Man_Jr]

Because cranking it all at once could crack his floor joists.

 

[unstopable4700]

my theory is moisture plays a large part in wood bending w/o cracking. a little moisture allows that wieght to bow the joice. so in theory you should be able to correct the bend slowly w/ the same force that caused it. well a little more i suppose. still see no rerason to drain the tank. it is static load.

If he took the water out I am sure the floor would raise a little, with it raised a little he could then put up the jack posts, I just can't find the words
