My worse nightmare finally come and i have to find the way to deal with it. Wife just call and let me know all four corner of my tank on the brace has been CRACKED. the middle of my tank is bow up to 1/2". I am currently away from home. I have call my friend who is specialize in sheet metal fabrication and ask him to build me a brace for the top. I will ask him to build me a top brace with thick metal to keep the tank together in the mean time. I will deal with the company who build my tank as soon as i get back.
