i have a 250 gal acrylic.i have had glass before and will not go back.acrylic does scratch easy but the clarity is really good.there are diffrent grades of acrylic some scratch more than others.i don't need 6 guys to move the tank 2 people thats it.my tank has not seen anybowing at all but mh use directly over the cross braces can warp because of the heat.
