Unless you're on the basement floor (or Concrete Slab) i would also suggest having someone look into your flooring situation. 2 four foot tanks and a 7 foot tank over the same joists is a boatload of weight... a quick guess is over 4000lbs.. not including any rock. or you standing over them to feed/clean/gawk...
