Recommendation for main tank overfill sensor

[GatorPharmD]

I noticed Michael installed an overfill float sensor in his tank. For a sensor that hopefully will never have to work, is a float sensor (mechanical) the best choice or an optical one?
Thank you.

I have used both the float and optical sensors over the years, my fear with using a float sensor above water is that it might get stuck if it gets encrusted with salt creep.

Thank you.

Yes Gareth is 100% right, I only used Float due to availability at the time of install.

I have 2 optical sensors on my system.

1) First sensor is use for top off my water. Its always wet. If the sensor doesn't see the water, it will open a solenoid and flow water to my tank, but on a timer. If it takes to long to get back to see the sensor, it will sound the alarm off and stop the water flow.

2) Second sensor is use for only 2 alarms. Its always dry.
a) It will alarm if my main pump stop working.
b) It will alarm, if my top off completely fails.

Been using these for a awhile, i have yet to clean them and never had them failed.
