Is 3/8 inch acrylic too thin for 240 gallon tank?

I posted this on the big tank forum as well, but thought I'd post here as well:

I'm looking to upgrade my tank, and I found a pretty good deal for a 240 gallon acrylic tank. However, I have concerns about its 3/8 inch thickness. Should I be worried about this? It will be a fully loaded reef.

Thanks in advance!
