Wow, you built your own tank?? You are a true hobbyist. I want to build my own tank too. I think glueing the 5 pieces of glass into a rectangle is easy, but where or how do I get the matching top and bottom support frame piece or whatever you call them to hold them together?? You know what Im talkin about right? I've always wanted to build my own tank because it looks so easy and tanks cost so much.. Im just stuck at the part where to get the matching frame for it.. Your knowledge is greatly appreciated..
