Thanks for the reply. The surface is pretty flat, but not perfect.
When I place the empty tank on the stand (home made), there's a little
bit more than a 1/16 of inch difference between the tank and the stand
(on one side). Is that good enough?



as long as it's not a large gap it will be ok. As long as 99% of the frame
is supported it should be fine. My 135 has about a 6" section that I can
slide a piece of paper between the full tank and stand, and it has been fine
for 16 years ;o)

Almost always true, but I have seen a tank that started to leak from a
its unsupported base after 20 years. The unsupported part was about 6
inch long. Glass bends into the gap if the sealer weakens. It is best
policy to arrange for 100% flat base support.
