tank is 1/8" leaning towards the back...okay ?

  • We are currently upgrading MFK. thanks! -neo
To use the hydraulic jack you would have to empty the tank because you can't guaranty even pressure on the tank while lifting. You would have to remove the sump to get the jack inside the stand to lift it too.

is there any place you can put a 2x edge ways to hit both front and back? then put the jack under that. a floor jack sits lower than a bottle jack. Or a longer sturdier board/metal to go longways in the back.
 
Off level won't hurt anything. As stated, as long as the top is flat and not twisted you have nothing to worry about. The extra water pressure on the low side is minute at most. A flat plane is much more important than being level.
 
I'm with Joe on this one..as long as the stand to solid and secure and the tank is leaning uniformly...I'd leave it alone. The main part of my reasoning for this is that you told us it started out totally level at first but only leaned after it was completely filled. Bieng on carpet...this is un-avoidable. Even if you DO go to all the trouble to mostly drain and then shim the tank this is no guarntee it will stay that way. In fact shifting the weight forward on a 240 tall will probubly cause the FRONT carpet to compress and reverse the situation.
 
well, the problem is that I can't remove the sump without removing the tank, I do have about 10" of area infront of the sump where I can push the sump a bit forward to have access to work on the back of the stand near the bottom, but still kinda difficult being the sump is pretty tall
 
Just to confirm and make me feel better and sleep better at night, I took some pics last night of the tank and stand.

First Pic;

The first 4 feet of the left side, This is on the long side of the tank

Second Pic;

The first 4 feet of the right side, This is on the long side of the tank

Third pic;

The center 4 feet, This is on the long side of the tank

Fourth Pic;

From back to front on the right side

Fifth Pic;

From back to front on the left side

Sixth Pic;

From back to front diagonally

Seventh pic;

From back to front diagonally with a shim to make it level.

Eight Pic;

The line is where the level sit to make it perfectly level

Ninth Pic;

The thickess of the shim right at the marked level, 1/8"

The tank is not twisted, the lengthwise is perfectly level, the tank is leaning towards the back ALL THE WAY UNIFORMLY throughout the back side of the tank

Welcome to the internet, where any 13 year old with a computer can be an expert. And yes, they have chimed in. Listen to Dr. Joe; he is experienced and knows what he is talking about. 1/8" is not a big deal.

Describe for us what is between the plush berber carpet and the dirt under your house. (what is holding up the tank and stand?)
 
I dont think any of my tanks are 100% level. My 100G is off a little, its on an EXTREMELY well made dresser with a 3/4" piece of plywood under it for backup. But the problem is that my home was built in the good ol' days none of the floors are perfectly level. They are structurly more sound than any new house built today. Id say mine leans around 1/8" to the left side perhaps a smidge more. I to agree if you have a structurly sound stand, and your floor is stable for the tanks weight...dont worry about the minor unlevelness. Most flooring in peoples homes arnt 100% level to begin with.
 
I have a question...and no I'm not picking on anyone...but....
The most accurate level on earth is a water level....as in water...the stuff in the tank...
If you can't measure an eight of an inch differance in the water level from the front to the back....or side to side for that mater...then your tanks NOT leaning an 1/8" of an inch....you said that an 1/8" SHIM under one side of the level braught the bubble back to the center....thats NOT the same as bieng an 1/8" out.
I've personally seen quite a few tanks do the same thing even though the water WAS level. The differance turned out to be in the plastic frame of the tank.
 
My water levels are all a little off from being a straight line, and then the level on top of the tanks are off a little. Could be the frame work of the tank to as you mentioned...but then I stick it on the floor and have the same results.
