well if you have a dirt crawl space the ground is going to heave and fall enough to move the floor or drop far enough the supports wont work then you would want to sister all the joist the tank will sit on, if you have a concrete floor in the crawl space it is probably below the frost line and you can support the floor with cinder block or floor jacks, and if it is sitting right on the main support beam you should be fine is that better?

:iagree: sounds like you're in construction or did a lot of homework.
 
thanks skat man not in the construction biz i refuse to pay my hard earned money to someone when i can do it so i always keep up on local codes new techniques and products but the best way to sure up a floor is to sister the joist with 1/2" or 3/4" plywood
 
lol... i know im EVIL, but i have yet to see a "house roof collapse" due to an Aquarium lol...

On a more serious note, try to get more info from the landlord, and try to get an EXPERIENCED builder in to see it...
 
the main reason i'm doing the jacks, is because even though the tank will be over the main support beam, it will not be centered over the support beam.
Each "_" is 1 foot of the tank. "|" is the beam

yay diagram!

I mainly bought the jacks for under the far left side. Thanks for the advice to sister the jacks; i may not be able to right away, but I will sister them at a slightly later date.

Anyways, this is how I hope for it to be. Here is my diagram again.

"_" one foot of fish tank
"|" main support beam"
"i" floor jack

eh its not exact. the main support is a little over a foot and a half to the right of the middle. But something along those lines. I have a 4th for just in case. The jacks will all be connected to each other, and I will later add more support to make sure they don't fall over.
 
I am supporting my 240 with 2 floor jacks that will sit on 2 concrete blocks. There will be a 4x4 perpindicular to the floor joists to run the entire length of the tank plus 2ft on either side of the tank. The tank will be sitting perpendicular to the joists along the main support beam of the house. I also have overlap of where the joists are butted next to each other in this area.

All that nonsense aside.... Just do it like bderick had posted and you'll be fine.

You'll be good. Just make sure you have a solid foundation for the jacks.
 
Since it is a dirt crawlspace, what is the best way to even out the dirt so I can get them all at even level? Or should I just have them connected to a board at the top like in the example pic, with feet on each one?
