Sorry for the really stupid question, I've had to get rid of my wooden stand as I couldn't get it level so I've got a metal stand like this which was much easier to make it level and going to get a new 60l tank today. Do I have to put a piece of wood on top of the stand before the fish tank goes on or does it just sit on as it is? Just got an image of the bottom of the tank falling out through the hole
