Well, that part is simple: for all practical purposes 1 liter of fresh water
has a weight of 1 kg.

So let's do it in ISO units: 8'x4'x5' is about 2.4mx1.2mx1.5m = 4.32 cubic
meter

In other words your are dealing with a tank of about 4.32 tons of

It's not the weight that's gonna get you it's the cost of the metierials
to build a 5 foot tall tank. Look at all the big tanks you see, 100, 200,
300+ gallons. Notice thet're not that tall? 2' max? That's cause the
thickness of the glass/acrylic you use is a function of the hight of the
tank. Five feet talk is absurd for an aquarium made freom glass or acrylic
you'd ned 1" glass about $100 a square inch or something stupid.

Best thing to do I think wold be to buuid this monster tank out of
marine plywood into the house and only use acrylic on the front
viewing glass.

I've seen this done, as a kid a guy in Hamilton Ont. named Stan
Winwood had marine setups in his house in the early 1970s
including one 800 tank built into the wall the same as
described above. Sweeeeet...
