Trouble leveling tank

[lilredwuck]

I have a 4' Johnson level and a 6' tank. If I put the level on the right side it says I am dead even on. If I put the level on the left side it says the right side needs to go up 3/32 of an inch. I have shimmed the left side already 3/4". This makes no sense to me.

It might not be level front to back and twisting the tank. I just leveled my 3' cube and had a similar problem. I shimmed the front right and back left corners, then sorta balanced it level and fit shims in the other corners to hold it there. If the tank is completely empty you could add alittle water to it to see where it pools up and at least start your adjustments by that. I dunno just some ideas. Good luck.

Is it glass or acrylic? If it has trim pieces, I would check that they are on correctly.

if its glass, the glass edge cannot be bowing downward. physically impossible for it to be straight and level, and then not 1ft over. (unless it just isnt cut straight.)

Glass 180 black trim. This is why it is confusing me so much. Carpenter by trade, and the only thing I can think of maybe the trim isn't on right.
