I have 2 innovative marine rimless 20 gallon tanks I had built a stand for both side by side. Built a 2x4 stand with a plywood top and put down a foam aquarium mat. I hastily filled them up got lights on and filters running and noticed one corner of the tank not sitting on the pad. Should I be concerned considering it’s not a lot of water volume or would I ship that corner with something? Any suggestions would be appreciated thank you
