Sorry to be a pain in the derriere again guys, but I need a little more advice with this slightly larger tank...... This time about its stand though..... Right, the tank fits perfectly on the unit, edge to edge perfect.... BUT.... it has a silver surround that is sealed on the base and this will overhang the unit by 16mm (so 8mm either side). Is this a problem? as if it is I will cut a base to put under it, or do the simple laws of physics apply and the only real downward forces will be supported as the glass will not overhang the unit?
