Big tanks and floors

Hello; First a question. Is the concrete floor in a basement or on the upper floors of a building? I ask because maybe ten years or so ago a similar topic was discussed. Seems there is a general belief that upper story concrete floors do not have load limits the way wooden joist floors can have. Someone posted useful information about the subject. I suggest a search on this site. Bottom line, if memory serves, is concrete structures do have limits depending on how they were built. A basement slab have much less of a question.
The carpet might affect a tank depending on how it is put down. Seems unlikely the wooden tack strips would have been used around the perimeter of the room. But if they were used such would make the base of a stand hard to level. Very likely the carpet was put down some other way on concrete. I have put it down using a type of glue.
The big issue with carpet in a fish room is mold. Even on a concrete floor the carpet can form mold. There will be spills and there will be high humidity in the room. Best case is carpet and pads (if any) do not have any organic content. Lots of carpets are made from petroleum for a long time. Even so i would be concerned about mold to some degree.
I recently pulled up some peel & stick tiles from a bathroom and laundry room. Found some mold under in places on the wood product flooring. I treated the flooring to kill the mold. I then bought some mold killing primer paint and put a few coats of that down. I then painted over the floor with an enamel type paint. I debated what to cover the floor with. Decided to see how the floor held up after a year. Looks good. I am going to scrub the surface again an check the condition. If it still looks and feels good I got some epoxy floor coating I will try. The enamel paint held up well.
Sorry for the long reply. Were it me I would pull the carpet and put down something else in a fish room. I did so in my fish room. Put down the commercial type vinyl tiles.
Good luck

I'm facing a similar situation. Conveniently, I'm a construction inspector and have worked for an engineering firm for half my adult life. Here are a few things I've come up with.
My situation: I have a pair of 234 gallon aquariums I'm building a rack for that allows them to stack. Lets call it 6,000lbs. for water, aquariums, stand, sand, decor, etc... The tanks are 6' x 2.5'. The stands spread that out to 7' x 3'. So that's between 285-400 psf (pounds per square foot). We test soil bearing for homes all the time. Foundations typically require 2,500 psf with slab area being 1,500 psf if they did a sloppy job. So they slab floor is plenty strong to hold my tanks.
I suggest running the numbers for yours, but I'd be shocked if you exceeded a safe threshold.
As for the carpet...
Check for the tack strip. Not only will it throw you out of level, more importantly it'll throw off your weight distribution and cause a concentration point.
The carpet will compress, and will do so rather evenly. I don't see it being a problem at all structurally.
That said... skjl brought up a great point about mold. I'm struggling with that same decision myself. I don't think there is a "right answer" but... after himming and hawwing... I'm keeping the carpet. While putting a couple of other moisture controls in plan in place (tanks sitting on 3/4 ply, ply oversized to catch spills, dehumidifier hard plumbed for constant use).
Good luck and keep us posted!
