So tanks been in for about a year and I noticed the water on one side closet to my wall is 1/4 inch lower then the other side. I did all my previous shims at the bottom in between the floor and the stand. This time around I want to put a shim now between the stand in the base board one on each side where its unbalanced it will be far easier that way then trying to lift tank baseboard and stand. Will this create a issue? I have 1 inch base board not standard 3/4 inch very heavy and 1/2 styrofoam. I am only concerned because because its off a quarter inch at only 4 feet tans is 4x4 and as you can see was originally a rimless tank I reinforced with euro bracing to prevent failure.
