120 Gallon Rimless Tank and Stand Leveling

[Steve Wallace]

Hi everyone,

This is my first post asking for help.

I just set up a 120 gallon rimless tank and stand on a carpet surface a few weeks back. I was very meticulous about making sure that the stand and tank were leveled before I filled it with water. It has now been 2 weeks since I've filled the tank with water and as expected, the carpet/floor has settled a bit and the tank is slightly off level. Side to side is 100% spot on. Back to front is 2 millimeters off. That's less than 1/10th of an inch.

Question: Should I drain and try and level the tank or is that super small front to back off level good enough to keep as is?

Thank you in advance.

Are you measuring from the ground up to the tank with a measuring tape or are you using a laser/bubble level and measuring from the top of the tank?

I would not worry about 2mm unless your on a concrete slap you are never going to be 100% plum. If your tank was largely off then maybe, but for 2mm I wouldn't worry about it.

You can also shim the stand slightly without emptying it, I have done this on my large tank with a car jack and metal shims when I first filled the tank. If you know and apply basic load transfer logic its not a big deal to do, but do this at your own risk.

I'm using a bubble level and in order to be exactly smack in the middle, I need to lift the bubble level up 2 mm at the front to make it dead center. The bubble is within the two lines already, but i was wondering if it had to be literally smack in the middle.

I would leave it alone but check again in a month or 2. Thats 1300 lbs of weight in a very small footprint.

I agree with this.

Nothing wrong with monitoring it, but unless your on concrete, you are always doing to get some settling.

+1 on shims

Already posted above... but 2MM is not enough to worry about. Keep an eye on it, make sure it doesn't keep settling. If you really want to, next time you do a water change, and the tank level is down a bit, drive a shim or two in under the stand (NOT UNDER THE TANK!). Or... not.

My tank settled a bit too. It's a rimless 140, 1/4" low across a 5' spread.

Eh.

You will need to bulldoze the house and rebuild at level for the 2mm... haha jk... I agree with above comments Welcome!
