was thinking about taking a large poly tank and putting a clear plexi window in the front,securing it with epoxy or silicone and bolts\washers every 3 inches.IF it all holds I'd build a wooden cabinet around the tank with 2x4 and oak plywood.I was told I couldn't seal the plexi to the poly tank,does anyone see a problem with this???
the tank would be roughly 6 x2.5 x 3
