Ok. my lfs has a long stand with two 150 tanks side by side, said he has had it like that for 6 years. OK I have 2 15 gallon colum tanks i want to sit side by side. I have an old all wood dresser; they fit side by side, but what constitutes that it will hold them up. same as if i have to make a DIY stand. Is it just the amount of bracing. I know a 125 stand won't hold a 400, but I was just wondering about stand in general.
