I have most of my tanks currently with double stands, due to wall space. Do any of you know if it is possible to make a 125 gallon stand that can hold 2 tanks? What worries me on this is that on the front if would be a 6' length with no bracing (since you have to put the other tank below it in the stand). I'm thinking that maybe a 4.4 on the front would work, but not sure. What do you all think? Whats the biggest double tank stand that you have built?
