suggestions if 180 can work on main floor( moved from random thread lol

your joists are stronger than you think.i've had my 220 with 45 gal sump with no problems.you also have bridging every 7 feet to stop any sway in your joists,plus with the subfloor nailed or screwed down,makes for a very stable floor.you have to remember,the weight of your tank is spread out over a couple of joists,and your not putting a couple of hundred pounds per inch on the floor.a quick test would be to jump onto your floor from a 3' height.an average 180 lb man will land with 3600 lbs per sq.inch-more than your tank would weigh
