leveling large tank question

[serpentman]

Its been about a week since I filled my marineland 300g. I think the stand has settled a bit as the bubble has drifted a bit to one side. Although technically, its still within the lines, I wanted to check here, do you think I should be concerned presuming it stays were it is?

Don't worry about the bubble on a level. Drain enough water (maybe an inch) from the tank so you can accurately "eye-ball" and measure the difference in the water level from side to side and front to back. For example, if you have a 8-10 foot tank and it is only 1/4" from the left to the right, you are probably okay. That same 1/4" from front to back in a 2-3 foot width, that is a more significant concern.
Is your floor likely to continue settling?

JMHO.

When I measure it, its off 1/16" front to back. Side to side its pretty about the same. The floor itself is a slab and shouldn't settle much more. Actually I think it was more of a case of the stand settling a little.

1/16"

1/16"

That's pretty close over a long span - sounds like you're on the mark..you could always try a thin composite shim - tap it in until you're perfect...When you change one side watch it doesn't screw up the opposing sides...
