I am in the process of building a stand for my new used 180 aquarium. I am almost done with the stand but when I put my 6' level across I notice some irregularities in the stand top. The most is ~1/32" but I am paranoid that it is not better. Would you worry is there was a slight wave to the top or just let it go. Options I have thought of to fix the problem are foam (have read mixed review with glass tanks) or a self leveling expoy sold at lowes for "wood shine" that I would pour with a mold to make a perfectly smooth top. Please all input welcome.
