Id go acrylic on a tank that size. And would also recommend setting it up with either external
overflow boxes or ideally even a coast to coast
external overflow box if you have the luxury of having a tank built for you. The coast to coast is a nice added benefit, but the important thing is that you have external overflow boxes. Nothing to get in the way of your reef or to disturb flow patterns.
Im not sure who makes tanks in your area. I would try to find someone good locally as shipping a tank that size will add roughly $500 to a tank that is going to cost $2000-3000 to have built in the first place.
