I'm Messing around with plans for my 311gallon Plywood tank. I was wanting to know instead of painting the tank can I Use a pond liner and seal it to the wood before i put the glass in, with silicon and 1/4"aluminum strips and then seal the glass to the aluminum. I would put the liner in with silicon, then put the metal strip on top of that with more silicon and then a TON of screws, Then silicon the glass to the metal strip? Also i seen a guys tank and instead of painting the tank, he used the thinest plexi glass he could and kinda made a Tank inside a tank... understand? the plexi was the waterproof and the wood was the strength?
