Ok after some reading. I think I get it. Need 1 tube from your friendly neighbor hood Wal-Mart. A few drain plugs. A good top. A few fish tank air machines and hoses. Some grow rocks. Now my question now is what is the minimum height I can go with? I plan to find a low very wide tube or a few tubes. This gives me a few ideas. I need to find a camera somewhere to log all of this.
