Anyone know how to fix a leaking 5000 gallon steel water tank on a concrete

One of two tanks is leaking from the bottom. Not much, but enough to keep
the concrete always wet (which likely is rusting it out even more).

I can't figure out how one would go about fixing this kind of leak.

find and weld the leak if you cant try to put self leveling cement on the bottom about 4 inches ,this is not a lifetime fix
