100 gal tank vs hardwood floors over crawlspace?

[MurphyLong]

My house isn't even 10 years old, and I have a crawlspace. I put my 110 +40g sump in what I THOUGHT was a good position on my floors. I was wrong. After a few years, the tank and stand started slowly leaning to one side, and I had to take the whole thing down.

There was less than 1/4" difference from L to R when it started, and within a month, it was almost half an inch. That's when I took it down.

A few years or a few weeks?

We'll be monitoring it for the first few weeks with a level. It's perfectly level at the moment.

the jacks are cheap insurance. when I setup my 90 gallon my floors felt a little bouncy around the tank so rather than hope I bought $100 worth of jacks and a few 2X6's. now it feels like i'm walking on concrete. planning to make a closet around the jacks to make my wife happy.

I am going to bet that structural engineers did not design any of our floors with a massive weight like a tank in mind. It may not be a problem right away, but over time it certainly could be. Listen to those that say add jacks, better safe than sorry...:beer::beer:

Very true. We will probably pick up a few jack supports from Lowe's and put them underneath it before we add any water -- the tank is going to be dry until July regardless as we're leaving town for a week at the end of June and I don't see the point in stressing over being gone after having just set up a tank.

It was setup for at least 2 years and was perfectly level. Sometime in year 2 it started leaning.

Interesting! We will be moving it in about 3 years anyways when we buy a house. We'll keep an eye on it.

How would one find the beams in an apartment that one is renting?. I'm thinking of putting in a 150 gallon tank with a 50 gallon sump by the window wall.

A lot of times, apartment floors are concrete and steel. The only way you'll know for sure is to contact management, and hopefully they don't try to jack up your rent.
