So I already posted this on MFK but I am sure there are different members on both and I want some good opinions. I stand has a wave in it, the center of the stand is aprox. 1/16th taller than the outsides. So the tank is sitting on a slight arch. I was told If I put down a 1/2'' piece of foam board down that it would be ok. Is this true? or should I just shim the hell out of the tank. It is a 125.
