| | Re: Acrylic Aquarium experience needed!!
Acrylic plastic creeps when under stress - it bends with the stress, and after some time it retains that shape, until it is put under more stress, when it bends again. I had an acrylic tank about that size, used it for about 5 years, gave it away, and it was used by that couple for at least 20 more years. I gave it away because I didn't like the way it was "ballooned" out from the pressure, and the small scratches all over the inside. But, it certainly lasted for a very long time.
