- I would like to build a solid state device that would turn off a water
- pump in my aquarium if the water level drops below a certain level.
- I am willing to look at prefabricated stuff but would prefer to build it
- my self.
- I would like to put the level sensor on the prefilter which hangs over
- the back of the tank and the rest of circuit in the cabinet below the tank.
- The reason for the circuit is mostly to save the pump, which relys on water
- for lubrication, shoud it start to suck air.

- Many thanks in advance!!!
