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

instead of doing this in the random thread ill disuss it in here.. here is a floor plan (not to scale just roughly).. the tank will weigh aprox 2500 pounds soaking wet. i think as long as there are not mosh pits inout living room we should be ok but your input and thoughts are appreciated.

2?'s

Distance from beam to outside wall ? Floor joist direction ( guessing 90 degrees to beam )

distance aprox 10 to 11 feet from wall joist is 90 degrees to beam. beams are 2 x10 construct x4 to make the beam. also noticed hen i whent to check the lower red line is actualy a beam as well not just a load bearing wall tis how i saw that it is 4 2x10s the outside wall is a reinforced blockwall done previously to me buying home. and done within the last ten years. the huse is 1300 sq feet

Personally, and this is just me.. But If I ever had a tank that size, I would put teleposts below, or add some framing to help support it

that is the problem.. it is a finished basment forour daycare dont have the room just to add a random telepost.. but i will tell you you can jump aroundonthis floor and she dont sway or flex.

in the end i stillhaveto fixthe crack in the tank and if it will be too heavy with stand and sump then ill just cut it up and make it a 120g tank that fits on my existing stand. an upgrade is an upgrade.. the 180 is ony costing me 150 bucks.. the glass alone is worth more if i was to build from scratch.

but when your wife says she would prefer the 180 than a 120 then you find a way to make it work. lol

Now thats a good Mrs you've got!

i will never complain other than wheni takeher to bayside corals.. she will find the most expensive coral and want it

joists
 

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!
