I have an older 180 gallon tank with a corner overflow on one end. (I don't know what brand it is though I am guessing All Glass.) In the center of the top is a 2 foot wide piece of glass that is setting on or glued to 2 pieces glued to the front and rear of the tank. I would like to come up with some other type of bracing for this tank that would allow me to remove the center glass. It is not clear anymore and I am sure that it cuts down on the lights properties as well as making it difficult to work in the tank as is necessary on occasion. Dimensions are 72 1/2 by 24 1/2 by 25 tall with 1/2 thick glass. Anyone have any ideas? Thanks
