Concrete Floor Strength

  • We are currently upgrading MFK. thanks! -neo
A concrete slab has to be 6 inches thick PLUS.. That kind of concrete can handle ANY size aquarium you want to get (assuming they followed code and used proper amounts of rebar). If you're still uneasy place the aquarium on an outside wall to ensure it's at least partially sitting on the footing (and probably on piles too considering it's an apartment complex).

I'm getting 175 psf and a total load of 2,100 lbs. That's not likely what your floor was designed for. There is no practical reason the builders would build it like that.

Bath tub examples are not good ones to use. 1) the tubs do not hold 180 gallons. 2) the builders know in advance where the tub will be.

Your tank will not be over a bearing wall; at best near one. You don't know what type of concrete they used or how many/what size/type rebar, or whether there are any defects in the construction.


If you look at the link, their comments are specifically along the size of tank you are discussing.
 
I had a 240g in my condo for over 25 years and it's still solid as a rock. Your tank will be fine.

^with wooden floors, is it in a old building if it is, I don't want to risk it.
 
When I set up my 750g in my house I did all sorts of research. I can't remember off the top of my head but 4" thick concrete has a tremendous crush pressure per square inch. Make sure tank has a full base sitting on the ground to distribute weight better. Not just 4 or 6 legs making contact. You will be fine with a 180g.
 
IMO if its near a wall it will be fine.
