It is funny who you speak with regarding the support. I spoke to a contractor and after we did our calculations he seemed okay it. I have 2X10 joists every 16" and on top of it is 3/4" or 1" particle board. Then from there are real wood floors. I am thinking after speaking with him, a couple guys who do tank installs here in Atlanta, that I would feel comfortable with a 120 and 40 gallon sump.
