It really depends on the tank. For rimless glass tanks it is recommend to have some sort of foam or barrier to distribute weight evenly in case there are some minor gaps. Some acrylic manufacturers say that you should use foam underneath their tanks, while others say dont. For rimmed glass tanks, no foam, as black plastic rim on the bottom does what foam would. Putting foam underneath rimmed could cause more issues than good, as you could create pressure points that otherwise wouldnt be there.

Best thing to do is reach out to manufacturer and ask them directly, this way you cut out any guess work.
