100 gal tank vs hardwood floors over crawlspace?

[lizri]

Hey all! I'm picking up a 100gal tank today that will have a 40 gal sump beneath it. It occurred to me today that it will be sitting on hardwood floors that have a crawlspace underneath (we live in a single story home). Is there a certain way I should orient or position the tank to ensure its weight will be supported? Or do I not need to worry about it with a tank this size? Thanks.

Make sure it runs across as many joists as possible.

I did add supports under my 120 with a 70 gallon sump, but it probably wasn't necessary. The easiest method is to add a few of the adjustable mobile home tripod screw supports.

So long as your home is not really old you shouldn't have any problems supporting a 100G + 40G tank without doing anything special..

Cool. The home isn't really old but we will check the orientation of the joists and position the tank perpendicular. Thanks!

Hardwood floors should be fine without support, they're much stronger than the osb material used in more modern homes.

A lot of people make a bigger deal about this then it really should be. Unless your house is really old, you should have no problem putting a tank on a floor. I've had 125+g tanks on a 3rd floor walk up apartment, a second floor apartment, and now i have a 180 on the first floor of my house. The 125+55 sump on the second floor ran parallel with the floor joists too.

i seen the term "unless your house is really old "

It should be if your house is older it will be fine . if its new and built with modern floor joist systems and shabby Carpentry that comes along with modern mass produced construction you should be fine...

This.

I got mine this way over long plank dark hardwood. It's a 6' 150 with trigger systems sump. Anyway it weighs a ton and does fine. Just make sure it runs across joists and make sure to use wood shims to level. My floor was so out of level I had to use around 50 shims to level out my tank (i own a granite shop for a living, so I know what I'm doing)

My house built in 1945 with a crawlspace (1' shorter then conventional)

I added support jacks under my 150. The floor was a little bouncy and that made me nervous. That said it was running parallel with the joists (no choice).

They are cheap and with it being in a crawlspace, I didnt care what it looked like. It's worth the piece of mind for me.

One thing I did for my tank that sits on a hardwood floor is built a small platform for the stand in order to add an extra barrier between the tank and the floor. No matter how careful you are there will be water splashed in the stand I didn't want anything getting soaked through and wrecking my floor. It's probably overkill but it helps me sleep at night lol.

Care to correct that? Didn't make any sense to me..
Shabby carpentry makes it fine?


Standards of min..40psf/span tables,etc.. weren't around "back in the old days".. Not to mention rot/weakening from age,etc... hence why I make the "old = questionable" comments about this..

Willing to bet my oh so very old house bones could hold most tanks better than many new homes.

Also, if you keep it against an outside wall the concrete footings will also hold a lot of weight.

 

[lizri]

We ended up placing it against a load bearing wall in the living room, the house is well built (built in the 50s I believe?) and has been renovated a couple times since. It feels sturdy and the crawlspace looks good. As per water splashing, I'm pretty crazy about cleaning, and it'll have a water absorption mat (got it online a while back, can't remember where...it absorbs spills but the bottom is waterproof so no water bleeds through onto the floor) around the outer 6" of the stand, and the guy who built the stand lined the entire interior with waterproof lining.

From that pic?... well...yes... I would take that bet

Forgot to add that it is level, that was the first thing we checked once it was in its permanent home.

My house was built in the 50s. Im not worried about it supporting my 65g tank at all. Old school oak flooring is solid.
