Seems that a simple micro-switch attached to a float would work fine.  The float
would be attached to the lever of the micro switch.  The pump motor is in series
with the micro switch.  When the float level gets below a level YOU consider
safe, the switch opens and stops the pump.  For a analogous system, take the
cover off of the tank of your toilet and watch how the action works when you
flush it.  If needed, one could get fancy and have an extra tank of fresh H2O.
When the water level in the main tank drops below a specified level, a second
pump is started to pump fresh water into the tank to keep the filter pump
operating.

Just an idea.
