This topic ought to be a sticky somewhere. There are a lot of different opinions on this which is why I get concerned.
The tank is 2' deep by 6' wide (typical 180') and has corner overflows.
I have heard some say that my overflows won't work right being a 16th of an inch off.
I have heard it causes stress to the tank. I wish someone with a lot of experience could speak up, I have a few years and my opinion is it will be fine, but I like to hear from folks that have already had big tanks and have dealt with the issues.
The stand is made of wood and expands and contracts a bit anyway. I would also like to know the strictness of the tank makers themselves. How exact is the trim and silicone.
