Is this good enough for support??

A single stub wall in the center will carry the weight just fine. A closet in that spot would be great too.
But at the same time, nothing at all would probably never have an issue too. But a little over engineering is seldom a bad thing.

Maybe we're not getting the same impression from his photos

I see a small piece of plywood under his jack post. If it's larger, that would explain me talking about a larger plate of steel
If it's a length of 2x6, it's still not sufficient. Either way it will compress and would be better suited with something to spread the load out farther, away from the post, to alleviate any stress on the floor directly under the post

I agree with you saying he could just adjust the post as the wood compresses, but that's not a 'safe' method. As I said, the wood could also split, and then the whole thing is useless

I'm unclear with your statement;
"I simply said the wood and the 1/4" steel would displace the weight to a similar footprint"
I was talking about placing a large plate of steel under the jack post to spread out the load. I never mentioned any wood in my idea

What do you mean ?

I would post more pictures but can't. I have 2x8 under the feet as I thought it may spread the weight a bit more. The tank is sitting on two outside walls but running with the joists. The basement has a wall already there. Then I made another wall about 4-5" in from there and sat my stringers (hope that's the right term) on the wall then have the 2x8 doubled up sitting on the jack posts. I'm not that fussed about using this space so if its better to build a new wall and remove the posts I still can?? Thanks.

How far is the span of your joists in this area?


flicker is an easy way to upload more photos.

Joist span is about 10' to the iron bar that's in the middle of the house.

2x10 joists? Looks like it's an older house, are they hardwood joists too? Or standard lumber.

So 10 feet from foundation to main load support?

You have nothing to worry about. Build extra support under the tank if you wish. But it's not going anywhere.

I might build a simple wall in the center of where the tank is, but it would simply be to take a bit of the bounce out of the floor for the fish tank. But I probably wouldn't do it until after I had the tank there and full to see if it's even an issue that needs to be addressed.

I am simply stating what I would do. I may not be an engineer. But I deal with all forms of construction trades every day, and for significant loads.

Just think about how much weight your living room is holding when you have a little party, and that's a live load which is significantly more force than the realistically static load of your fish tank. And the guest are normally in the middle of rooms, not hugging the load bearing walls.

Thanks. 2x10 old house from the 70's solid wood. Yes 10' from wall to main load support beam. So ill basically leave it as is then?? I'm happy with it I think and I shouldn't have any bounce with it like it is. Thanks

His photos are small. But it looks like a ~10" piece of 2x6 under the feet of the posts, well at least the one that I can see.

The wood will hardly compress. I seriously doubt it will split. His biggest issue with the wood is that it is not pressure treated and directly on the concrete.

The part you are unclear of is I am saying the wood he has will be as effective as the small thin piece of steel that you are recommending.


He is putting a tiny load on this part of his floor, he's not putting a 40 ton Leopard Tank in his living room.
