    Rimmed into rimless

    Do I need bracing for a tank that is 48L12W16H and the glass is 6mm thick. It has a rim but I want to take the plastic off to make it rimless. Total gallons is 40 and the original tank had one brace down the middle.

    The Aluminum will be stronger than the Plastic trim you are removing so, provided all four sides are braced, you should be fine and.....IMHO.....it will look a helluva lot nicer...Click here to enlarge

    You most definitely will need to brace a tank this long, as it will indefinitely be able to bow once the pressure from the water is present.

    I don't recommend taking the rim off of a tank larger than 20 gallons, and that is without bracing, but it may depend on the dimensions.

    It's not the corners that are going to be the problem, it's going to be the 48" run of glass that is not supported with a trim on the top/bottom... The top being the biggest concern, as it blows outward while the bottom of that same piece of glass doesn't bow as much because it's siliconed (braced) by the bottom sheet of glass on the tank, creating all kinds of stress on that sheet of glass as it deforms... Even if it holds water intitially you run the risk of failure down the line, especially if it's say bumped...

    Nah I feel imma put aluminum all around, even the full run of the 48" so the tank will be encased in aluminum.

    In that case it's not rimless, and might be OK, a center brace would still be advantageous for a piece of mind if I was doing it...

    FYI with a little practice Alumi-Weld can be done by the hobbyist without much trouble, so you could build the frame out of aluminum as a single unit with a 'welded' center brace then drop on and silicone just like an plastic trim... Obviously don't weld it in place, the heat will crack the glass...
