Wobbly stand or uneven floor?

[Cody000125]

Hi All,

Hoping to get everyones input on how I can resolve this wobble issue with my tank. I just recently setup my new 100g, but noticed when walking heavily/jumping near it it wobbles very easily. I'll post a video down below of just pushing it lightly and it wobbles. I don't remember the tank wobbling when water wasn't in it, but I also never knew to test for that. I was recommended to add shims to try and resolve the issue, but I'm unable to reach to the back and putting shims on the other 3 sides didn't make the wobble any better or worse. I've removed them for now. I was measuring the floor and it doesn't seem to be perfectly flat, not sure if that would cause any issues. This is an innovative marine 100 ext if anyone has had and solved a similar issue. Could I of assembled the stand incorrectly? Or could my floor be uneven? Any suggestions or help would really be appreciated. Thanks!

Doesn't seem the insert video is working properly, here's the youtube link:

Have you put a leveler on your tank to see if the tank is leveled?

Have you put a leveler on your tank to see if the tank is leveled?

I did originally with a 12 inch level which to my new understanding isn't very helpful for a 48 inch tank :) I got a 48 inch level now and have these pics:

Here is the front seems very level:


Here is the right side of the tank from front to back:


Here's the left side of the tank from front to back:


Here's the back of the tank on the overflow from side to side:


Any input? Seems like left and right sides need to be lifted which I had tried yesterday with the shims and didn't have any luck fixing the issue.
