Lightweight DIY Aquarium Build

Keep in mind hydro static pressure works off of the height of the water column, not the length or width, weird huh.. so a 44" high tank will need a very thick piece of acrylic.

The aquarium itself will be no more that 30" high. Not 44" high.

I see you said you will only go 30" you would need minimum 1/2" with good bracing, I'd suggest 3/4" at that height.

Carbon fiber has a strength:weight ratio superior to fiberglass.

K Keightley Are you a renter? Assuming you are, I wouldn't mess around with non-standard methods of tank construction. If it catastrophically fails, I'd be worried about your legal position should the landlord come after you. I'd do glass or acrylic.

If you own the place, do whatever you like
