Only the top edge. Anyone successfully do this? I am planning a paludarium so the water would only be a little over halfway up. It is an older tank and the glass is 3/8" thick. It is 72" long x 18" wide x 21" tall. I may just try and remove the wood grain, assuming it is contact paper or some type of stickery thing. I figure I can keep the rim so if I would every want to add full water, I can put the rim back on. Just so you know I am not trolling, just curious. I saw threads where people were doing it to 75 gallon tanks and was just thinking maybe someone has done it to a 125.
