You should be fine with a 4" slab. Generally commercial Concrete has a PSI rating of around 5000psi. But that depends on age of the building and city codes for commercial building. But saying you have 3500-4000 psi concrete is safe.
1700 lbs for the tank
10,020 lbs of water (tank volume)
2000 lbs for the stand
700 lbs for rock (guesstimate)
400 lbs for various equipment
500 lbs for rock facia
your at 15,320 lbs.
with your tank dims, your sitting on 7200 sq inches.
15,320/7200=2.127 PSI of pressure on the ground spread out. Now your stand is not sitting completly on the ground, It has legs. so you need to figure you sq inches of of leg surface area on the ground, divide that into 15,320 and you will have you PSI rating on the ground. if it is under 3500 psi you are just fine. if it goes over 4000 psi I would bring in a engineer to test the concrete to see what PSI it is rated for.
I expressed some concerns about this earlier in the thread... I thought the response to my question was that someone had already come by and examined the floor.
Do you know for certain that it is 4" concrete? Where does this rating of 5000 psi come from? Of course this depends on the age of the concrete, how well it was mixed, the quality, how it cured, etc.
If there are already some cracks in the floor, that could easily degrade the psi rating.
It looks to me like that tank is positioned in the middle of the floor, a good distance away from any footers. I'm willing to bet that it is just loose gravel beneath the concrete.

Here in Minnesota there is a standard of 5000psi rating for commercial concrete floors. Residential is not as critical of course. But any building that is made the foundation and such has to made to code. That is what I am talking about. It is differant state to state and county to county and city to city but as a general number given 5000 psi is the rating that is pretty much standard across the board.
I do have to agree that it is probably class 5 under there but if it was built in the last 10 years it is 10-25 inches thick and compacted. there is also probably 1/2" rebar within the concrete. I would not be concerned with the weight. There is strict building codes when it comes to the foundation and poured floors of commercial buildings and generally are over engineered. I would not worry about the floor.

Shouldn't have to worry about the floor. The Internation Building Code specifies 5000 psi with 5-7% air entrainment using steel mesh, after 30 days. Usually a slump test is done at the pour, it is tested I believe, 24 hours, 5 days, 15 days and 30 days. That are on the test results that I recieve from the labs. I am going off the top of my head.
Concrete gets stronger with age and use. The only real enemy is the elements. Should be fine.

Thanks you guys..
I went that route because first I could not have doors with stone to get into the tank and if it was in wall from front and two sides then I could get into it from the back (if room and filtration was in the back. Other reason is to give people idea on how it will look using stone and cabinetry. The stone, work, cabinetry is very expensive but we figured if you want to do it then do it right. Fish can use a maid and I think I will be the one Æ'º . The owner of the building told me that he checked and is fine. We cut a hole in the other side of the building to check and it was about 4¡¨ thick concert that took long time to cut through. We also checked the gravel under is and is well packed. I brought some construction friends who work for Penn DOT and they said that I should be fine and all that thinking that people who did the floor followed the codes through the whole building. The stone frame is really heavy and I can find out how much weight in few days.
