Hi guys. I am going to start my 150 Gallon tank tommorow (hardiboard and drylok) and i was wondering if 1/8 inch glass (or whatever is in a 10 gallon) will be fine for a 10 inch viewing window?if not,i can do 3/8 laminated but i would like to keep the cost down. The window will be 20x12 and supported 1 inch all around it, so the viewing area is 18x10.
