Leveling an 77 Gallon tank

[lucky777]

So I'm finally moved into my new place and have setup my 77 gallon Mbuna tank.  It's an older home (110 years old) and it has beautiful hardwood floors.   My problem is that the floors are not perfectly level.  I installed a few floors jacks in the basement to try and level the floor out, but because of the duct work I cant move the floor anymore and the tank is still not perfectly level.  The left side of the tank is about 5/16 " lower then the right side.

Could such a small difference be cause for concern? It it possible for the left side to give out?

Buy a piece of 5/16 plywood and level it that way?
I don't know about the structure of the tank but the water-line would look crooked.  I moved and levelled my 55 recently and it's seems much nicer with the waterline not being on a diagonal.

There are products you can and should put under it that will let it level itself.   You can buy styrofoam at the lfs, or some people use those soft rubber like matts that you stand on.   A shim under the legs of the stand perhaps?

From previous threads I have read, it is important to have larger tanks completely level.

Hopefully others who have actually dealt with this will offer their solutions.

We had the same problem with our 75 gallon tank. We just purchased a few shims from the local hardware store and fixed the problem that way...

Good Luck!

I have the same trouble here, Old home, pine plank flooring. I used shims under the base of the stand. They are the same kind that you use when installing doors and windows. Available at any hardware store. I used 1/2 a dozen or more so that there was not allot of pressure on any one spot of the stand or floor. All you have to do is score a line on them when you have figured out how far they need to stick in and snap them off.
