Not exactly. Let's say your tank is 1.5' by 5'. Here's what I'd do. Make up four frame and panel assemblies 19" wide and as tall as I want tha tank to be. Two for the outside and two for the inside. Make the outside ones 1/5" taller than the inside ones to allow for a 3/4" rabbet top and bottom. Cut the 3/4" sheet goods 19"x60" and glue into the top and bottom of the outside frames. Space the inside frames equally and glue into place.
Now that's the simplified version. The width of the 4/4 stock used for the frames is a matter of taste but I'd probably use 3" wide stock.
Dan, it appears from some of your questions that you're a relative beginner at woodworking. Starting with an aquarium stand is a great way to get a lake in your living room. My suggestion would be to buy a stand or find an experienced woodworker to build one for you. If you're still interested in woodworking take some classes, read some books, build some things that aren't structurally critical. We all had to go through a few years of learning - and I'm still learning :-).
