Center Brace Question

[The Guy]

The glass centre brace works just fine, if you are concerned at all put one in front to back glass 3/8" by 3-4 inches wide. It's not hard to do and then you have piece of mind, 120 gallons looks great with all the water in the tank and not on the floor. Just my opinion

For piece of mind I would put a centre brace in better to have that protection there than waking up to a 120 gallon pond on your floor just my 2 cents worth

3/8" glass isn't thick, for a tank that size it definitely requires bracing. A center brace however isn't the only option, most tanks utilize a euro style brace as shown below. If your tank has this then you should be fine, if not, some form of bracing should be added.

My bad. it is actually 1/2 inch thick. I ordered a piece of glass and will silicone it in the middle. I also changed all the silicone inside it. Cross my finger it will hold.
