Ok, so I think I have a serious issue. I have filled the tank with about 50% water. It is sitting on 1/4" thick black neoprene. I thought the table top of my stand was level but what I'm seeing is that each of the corners of the tank is not being supported by the top beneath it. So my table top must have a slightly downward bend to it both towards the sides as well as towards the front and back. The tank is supported along the side as shown in the black areas of this mock up: Here is a picture of the small gap under the corner I'm terribly frustrated at this point so now I'm trying to figure out what to do. This tank has a phantom bottom and armored seams. DO I shim under the tank, or tear everything down and tank the tank off the stand and somehow plane it? Or is the tank ok since the bulk of the weight is being supported rather evenly across 95% of the tank? Looking for some advice.
