Well, I was looking at sites like glasscages, and they recommend 3/4" styrofoam under the tanks to help prevent seal breakage and even out the load of there's any un-evenness in the stand. I just had a thought and was wondering if this might work. At Lowe's, they have the weather stripping that you can put in door jams to insulate the door. They come in several different sizes as well. Would this work if it was placed around the edges of the stand so it's even with the edges of the glass tank? The ones I was looking at I think were 3/4" or 1" thick, and are soft.
