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

i realise that the joists are strong enough to an extent it never hurts to be 100 percent sure before you cave your house in. not to mention i live in a swamp where homes shift and move constantly from season to season. and am sure there is more to it than just jumping from 3 feet to test.

I have had my 180 with a 90 gallon sump and a 120 gallon set up about 5 ft away on the main floor for a while now...no issue whatsoever!
