So I am in the process of setting up a 90 gallon custom used tank with a stand. My floor is slightly off where I want to put the tank and I want to take every extra precaution I can. The tank is rimmed on the base so I know technically it is not needed, but should I used a foam mat under it just to be safe? Also wouldn’t a thicker work out mat work just the same as the black mat the charge a ton for?
