Schematic for 120 gallon aquarium

Yeah, folks seem to like that one .
There are more refined designs but that one is very forgiving for a new builder.
 
For a 4 foot wide tank, you only need a 2x4 top frame, not 2x6. My LFS has multiple 4 ft x 4ft tanks that just have a 2x4 top frame with 4 x 4 posts at the corners that go down to the concrete with 3/4 plywood on top. They have had these tanks up for 10+ years, no issues, no bowing / sagging.
 
You can always go watch king of DIY on YouTube. That’s how I started my build.
