Stand pics!!
Here the one I did for my 60:
I essentially made two window headers (pic 1), I did this because all the weight is transferred down to the floor and spread over 4' essentially. I used 2x4s as beams holding it together w framing brackets. I then cut out the sides and front (pic 2) these are held on w toggles and can be completely removed for easy sump access. I decided to burn the whole thing instead of painting, it hardens the wood and makes it mildew/mold/rot proof. I assembled the whole thing at a friends shop where I work to be able to be taken apart and reassembled: brackets holding the beams can be unscrewed, sides can be unscrewed, and top can come off, then took it home and assembled it in my office. This was the hardest part w this build as I had to make it able to take apart and out back together while stil being strong. I massively overbuilt it as I have a 120 that's the same footprint that I'll use when we move next year that I was going to use this stand for. However, I would have made a metal stand but at the time I only knew how to use wood. Learning how to weld now so that I can make a metal one for the 120 instead.
Here's a simple stand I made for my 55 rodi water tank:
