I am not sure what you are confused by, I read it a couple times trying to figure it out, oh well. But sure I agree with you as well you dont need a slab, makes it nice of course, but other ways around it.
How big is too big!! (floor)

One thing we need to account for is the fact that the weigh is not spread over the entire area. Most wooden stands do not have a solid bottom. We counter this by placing our tanks on sturdy sheets of wood to better distribute the weight.

I can hear my highschool english teacher saying that thing that english teachers love to say. You know what you want to say and the trick is getting your reader to not read it differently. Oh well. Just don't tell any english teachers
CHOMPERS;645291; said:There is some really weird math going on here, and the physics of water has changed too. It looks like it is time to rewrite all those text books.
Water USE TO weigh 8.33 pounds per gallon. That would make 180 gallons of water 1500 pounds. If on a 2x8 foot print, that breaks down to 93.75 lb/ft^2, or .65 lb/in^2. A wood stand will keep the weight within acceptable loading. An iron stand will not.
Also,
There are 144 in^2 in a square foot
There are 1728 in^3 in a cubic foot
180gals = 1500lb
tank = 300lb
stand = 100-150lb
W/D sump = 100-150
Misc equip = 20-50lb
substrate/decor = 50-100lb
fish = 5-20lb
.....................................
2270lbs = 142lb/ft^2
Not acceptable on any standard joist flooring, 1st or second floor, must be either supported from below or by adding to/sandwiching the existing joists. Tank would still need to either be perpendicular to joist and next to load bearing wall or perpendicular to joist and inbetween two loadbearing walls with not more than 12' apart.
I would highly suggest reinforcing the subfloor too, a additional sheet of thick high grade plywood beneath the stand would be good.
