just a FYI thread on my upcoming upgrade/downgrade.

I have an old house. Had an engineer friend come by and he said that my joists are overbuilt and the floor has a higher load bearing capacity then newer houses. Of course, you are currently on a cement pad so....

If the joists run perpendicular to your tank, you can have a bigger tank as the load will be spread out across more joists. If the tank sits paralell to the joists, you will only be distributing the weight across 2 joists or so... which is not good.
