I bought a 150 gallon long tank for a steal, from what I've seen I'm assuming it's a very rare tank (60"x24"x24") while transporting it to my house the bottom sheet cracked from front to back, the glass is annealed but I was wondering if I replace the 3/4 inch thick sheet of annealed glass with 1/2 inch tempered glass will that be fine? It also has three holes drilled on one side so I can run a freshwater sump. Also, while removing the bottom trim to remove the broken glass, the trim came off in four sections (one for each side of glass) is that normal for larger tanks? I was very careful while removing it so I didn't break it but that's just how it came off, the bottom trine frame also didn't have any cross bracing, is that normal as well? There was never any to begin with and no signs it used to have one that was broken off. Any help or advice is highly appreciated!!! Upgrading from a 75 gallon to this 150!
