I have read several places about how to build and acrylic tank and such, but my question is when you go to buy an acrylic or glass tank the biggest length ive ever seen is 120, is that pretty much the longest you would want to build and aquarium or is that just the biggest they would build it? Is that the saffest length or could it be built longer? I know your going to ask why would I want it longer, Im not saying I do, Im just curious. I ad an idea to build a 144x48x36 1" thick tank (1100 gallons) and didnt know if it would be safe not seeing any manufacturers making them this long. Any help or opinions is appreciated.
