Water Level Indicator With Anti Corrosion Feature

This circuit is a Water Level Indicator With Anti-Corrosion Feature !!
In this circuit i used some wires with different lengths to detect the water level.
But to avoiding Electrolysis Corrosion we have to using AC voltage instead of DC voltage,
To do that i used IC NE555 to generate a low AC voltage. 
I explained that in this video: https://youtu.be/wrMyt4tC5oQ 

Parts List:
IC NE555
Red LED (4pcs)
Green LED (4pcs)
Red LED (4pcs)
Yellow LED (6pcs)
Resistor 33K
Resistor 1.5K
Capacitor 100nF (9pcs)
Capacitor 1nF
