Re: [APD] plywood under tank?
The only problems I see with the interface between the tank bottom
and the stand top are:
If the stand top is not flat, is bowed up or down, the weight of the
tank will be supported over a very small area, which could possible
cause the bottom to crack.
If the stand top is rough, to the extent that there are protrusions
sticking up, those could locally stress the glass on the tank bottom,
causing it to crack.
These possible problems would apply largely to rimless tanks, having
no plastic frame at the bottom. When I make a stand I try very hard
to get a completely flat and smooth top on the stand, and I notice
that commercially made stands are the same. So, I have never put a
piece of plywood under my tank.
