Im going to go ahead and qualify all this advice as well as i've not seen your actual flooring. I really dont need to get sued after the floor collapses and causes 20K in damage. My recommendation stands though that you seriously consider the strength of your floor before you put that kind of load on it.

Something to consider: general design parameter for living space is 40lbs/sqf. the are under this tank will be facing loading about 10 times that.
