If you want to place tank in room as a divider,Just lay tank across 4 floor joists then take 2 2x6 and nail them together then make sure the length is enough to span the 4 joists and then nail that to the joists directly under where the tank will sit. Then just put 2 floor jacks... each between 2 joists . you can get 2 jacks, each can hold about 15,000 lbs each. It's what i did with my 210 gallon.
