Would this work?
tank with new saltwater + an air stone
A pump on a timer that runs a few minutes a day
an overflow in sump that runs to a drain or waist water tank
pump would turn on and pump water from the new saltwater tank into the displays, old water would overflow out of the sump into a drain. . .
???
what other things to consider???
