Hi everyone, I don't know if this is the correct forum but here goes. My mom said that I could build my own plywood aquarium but that I'd have to keep it in a manufactured home that we got off of Craigslist. It's a 1988 Oak Creek 16x80. We've done the floors over and the previous owner was still living in it, so it's sound. My question is can I put my 360 plywood aquarium in it and should it go perpendicular to the floor joists? The reason that I asked is because I see an I-beam under one of the walls but it's parallel to the joists. They run front to back, 16" on center. Either way, I plan on putting cinder blocks filled with cement under them. Thanks for the help.
