I cannot stress bracing enough. This spring, my 230G bowed because the center brace and one end brace came apart. The braces displaced some water and then the tank started to split. Wow...can 5/8-inch glass ever bow. I purchased some 5 foot clamps, emptied the tank, cut it apart and the re-siliconed it and the bracing before restocking it. It could have been a total disaster...especially when my wife found oceanfront property in the basement. The bottom line is that you need good silicone and bracing to help reduce costly mistakes down the road.
