While true they are not called "ceiling jacks" calling them "either floor joists or roof rafters" would even be farther off. Picture below is what I'm sure the OP is referring to.

Photo is of Dodgefreak8's crawl space support system. I believe he also has a 210g

correct ....initially I read the original message in a hurry and the term "ceiling jack " threw me off (in my post I was referring to permanent framing members names) ...a jack is just a jack lol ....
btw...this should work fine
 
The floor as constructed can hold the tank. My friend has a 300gal in his living room.
 
if youre putting it right on the main support beam no need to do anything

Please don't suggest this when the OP has an obvious concern and has already received very good answers. Putting a ton of water/tank onto an elevated floor is a cause for concern no matter what is underneath. Unless you have crawled underneath the OPs house and studied the floor joists, you can't honestly make these comments.

Maybe he can, but maybe he can't. I applaud the OP for recognizing the issue, asking advice and proceeding with correcting it. And I applaud the excellent suggestions others gave :)
 
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?
 
Alright.

I'm going to connect the jacks using a 6 foot 2x12 at the bottom, and attach them to the top of the crawlspace using a 6 foot 2x8. I was told using bricks isn't a good idea because they will crack over time.

Also, I have a 2 foot space to work with. The smallest jacks I have will go down to 1 foot 7". So, i should have plenty of room for these boards. any more suggestions before I do this?
 
yep. and if you dont wanna spend money on multiple jacks, use a bottle or scissor jack and a length of 4x4 that will fit between the jack and the joist, and jack right next to the pad you make, and install some permanent cinderblock pillars or even just some 4x4 or 6x6 pressure treated posts should work just fine. I plan on doing this to my own crawl space this spring to allow for a larger tank in my spare room. Landlords are almost always cool especially if you're the one footing the bill for upgrading their property and if you provide the labor.
