Can you elaborate not to slam the company but just to understand what your talking about, I had a local tank builder build my 600 gallon and would never spend another dime with them he assured me the tank would have 3/4” acrylic all the way per my request I told him I would pay the extra to have the entire tank in 3/4” he charged me for it, notified me tank was done and asked for final payment I payed right away when I went to pick up the tank it had 3/4” acrylic on the main body and 1/2” on top and bottom I was furious asked for a refund showed him email correspondence and he refused to make it right so at that point I just took the tank I had rented a uhaul box truck to pick it up with a bunch of buddies didn’t want to lose the money on that or waste all of my buddies time for that matter. With that being said tank has been running for 4 years no crazing yet but it definitely bows the top bows pretty good that’s what I didn’t want to happen especially for the price I paid. lesson learned will be purchasing next tank from midwest custom aquariums.
