I wanted to start a thread for some veterans out there to give me some advice on building a large tank. In my earlier build thread I mentioned building a 400+ gallon tank out of acrylic but I have recently given thought to using plywood and glass. I am wondering how well this would work? I also know I have heard of some folks in Australia building them this way? What do you guys think? Gloves are off, lets hear the opinions and ideas of all here please.
