What is the best way to brace a tank? My 135g tank is old and has no center bracing. I was just planning on purchasing a new top bracing system from All Glass but I'm afraid that my glass sides will be too thick for it. I tried to silicone 1/2" acrylic strips but it bowed when I put the glass tops and light on it. The reason I am bracing it is my current glass top is all messed up and I want to replace it. I bought AG's glass top for it, but it needs two bracing strips for the glass tops to rest on. Any ideas?
