You hook it up as an extra pump to recirc only, with a seperate switch,
leaving the refill pump to it's own process.

There is a recirc pump available thru BPS and other places that attach
to
the bottom of your tank for inlet, and attaches to the top of your tank
for
an outlet, just be sure to put a screen at the bottom so you don't suck
your
fish into it like a vacuum hose. You can use any small volume pump to
achieve the same results.

But that would prevent the well from draining and also remove the ability
to
pump in water from the lake. I'd still need that value in order to keep
that
ability.
