Hi, I currently have a 600 gallon tank. demintions are 10'x48"x24" but its 1/2" thick acrylic. It was made by a local guy who is pretty good! It bows pretty good and I live near train tracks that shake my house! It has been set up for a couple of years with no problems but I lose sleep sometimes! I have sold my motoro rays and want to upgrade to 1" thick Before i get some black rays. I fear after I spend all the $$$$ on the rays ill come home to a nightmare! I just tried to contact tenecor since they are close to UT, but they are out of bussiness? I remeber of a place in colorado but cannot remeber the name. If you know a good custom tank shop please let me know! thanks for reading this, Chris
