I would start from scratch and identify the unlevel surface. Concrete floor and hardwood doesnt guarantee a level surface. Check the floor, then move to the stand. And I would concur with Darth, as I have done this as well... Make a plywood/ styrofoam sandwich and the tank will settle out. I would want all the legs of that stand in contact with the floor, not shims then floor. And as you are moving, the ply/styro can be used where ever you are.


I may not be the Boss, but I'm ALWAYS right!

I agree with Dave, it would be best to identify the unlevel surface. Personally I would be uncomfortable with 3/4" difference, and would probably build a new stand to match the floor if it is the problem.

The room appears to have been a carport originally that was converted to a living space. I believe the slant to the floor was built to shed water that entered through the open entrance at that time. I did evaluate before placing the tank but unfortunately I don't have other options for placing this tank as all other rooms have raised floors as the home is a bungalow. Having said that the front to back difference in level is close to 1/16" and the end to end difference this morning is less than 1/4" with the plywood under the low end.

As for the sandwich with Styrofoam I'd prefer to not lift this tank again if possible and I would like it to sit as is in the stand because the trim on the tank itself is wood grain and would not match at all but is currently hidden by the stand. The picture with the tank I posted you can see how level the tank water is now.

I saw that in your other post regarding filtration, you were worried about the sump overflowing since it's in your A/V room....shims aren't going to cut it once that tank is filled......tanks of that size have to be absolutely level......even a small difference out of level long-term will cause stress fractures & explosions.....not a maybe, it will happen......I would more than strongly recommend you do 2 things...reinforce that stand....better too much support than not enough, & you definitely do not have enough, especially in the middle.....& again the best way to accomplish leveling is plywood & styrofoam, which will take out any imperfections. You can always paint the tank, & better to not "match" than have a disaster, which, IME, this is heading....You're talking around 1,800 lbs filled, just tank & water......just a heads up. :whistle:

The tank was on this same stand for the last few years. I purchased it off CL and just painted, stained and polyurethaned it. That's why the doors are still missing as I am waiting to put them back after plumbing is complete.

I realize the middle wasn't supported that's what I was hoping to here solutions to. While a solution was provided it is a different direction all together and not one I can do myself without the assistance of two other strong guys. as the saying goes there's more than one way to skin a cat.

I'd hoped someone would elaborate on how they might fill that gap. This morning I began shimming the backside of the tank. I did so in a parallel fashion rather than perpendicular. The resulting effect is much larger surface area being supported by the shims. The end result will be 10 contact points 180lbs each.

I would not trust that stand. You could easily measure some 2X4's that measured from the top of stand to the floor, get a impact driver & some wood screws, & screw them to that middle brace & the corner ones if not doubled up.

I would not rely on shims to ensure leveling. 1800 lbs + will compress this over time, & could go out of level.

Having seen 1st hand a few "bust-outs", & the aftermath, I would more than strongly encourage you to try & get some help to ensure that this will be spot-on level. Stress on glass is a funny thing; one day everything is fine, & then.....BLAMMO.....You will only get on chance...... :whistle:

My perception of what you stated was do what you say or things will go bust. Since I'm not in agreement and nobody on this forum seems to have an opposing view or that person just hasn't read this post . Which has left me in conundrum. I'm a very logical person and while I see your concern and I see how your solution would work. I do not see how it's the only one obviously you have been around and seen a lot as you have a ton of post. While I have very few on this forum.

Anyway, I was able to level the aquarium and feel pretty confident with the method used and it is level at all angles now. I also measured the water height and it concurs with the level 2" 1/2" all the way around. I've now raised the water level to the one third mark and will keep it there and watch the level before taking the water level to the two thirds level.
