Okay, finally about to start construction on the pond. Looking for a little advise. I am planning a 12' x 5' x 3' pond with a water height of 32". I want to do two 4'x2ft windows across the front. The total gallonage should be about 1200. Will half inch glass be thick enough to get the job done? Does anyone know a good place online to pick up 1/2" glass that can be drilled? Any other suggestions on window building and ideas please post because at this point I'm pretty unsure. Thanks ~Trent
