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.

Consider replacing the tank. There is a huge stock of surplus food and
chemical processing tankage your can find with internet searches, and
Yellow Pages in some areas. With a bit of luck you may wind up with a
stainless steel vessel of the right size complete with pipe fittings.
Transportation is not a problem as the size you need fits easily on a
flat bed trailer or roll-off. If more than one tank from the surplus
company is available, consider buying two if the $$ look good, and
installing both, keeping the non leaker. When the last steel one
fails, you still will have an adequate storage system.
