That looks like maybe a 84" or 96" by 24' or 30' tank.Did you by chance measure it while looking at it? I like the entrance method,though I would opt for steel over wood stairs.The painted interior is a good idea,it keeps psychology in order.Cheerful colors.Dark or dull colors would have a negative effect on human psychology.It appears he used existing threaded pipe filling ports as his penetrations.These will be too small to move enough air for long periods of time.Okay for short duration. He would have been ahead to swap over to grooved type,or Victaulic fittings.Much easier to service and more rugged and flexible. You don't need big pipe wrenched to tighten,only hand tools. I'd like to see him install some conduit and junction boxes.Tiddy up that wire spaghetti.
Thank you very much for taking the time to scope this thing out.Very informative.
