Agreed, you also might want to consider that if the tank is wider than the base it will be less resistant to tipping than if on a wider base.HarleyK;632038;632038 said:Howdy,
If the total weight indeed won't exceed the weight of the tank for which the stand was designed, then you should be fine without reinforcement. However, I would go to a home improvement store and buy a thick board the size of your tank's footprint (they will cut it for you). Then simply put that on top of your stand and position the tank on top of it. The board will prevent stress on glass at the overhanging sides.
Good luck,
