Overflow Sensor

[HB Fisheye]

I'm looking for an overflow sensor to shut off the ATO if it should malfunction. It's going into the filter area of a AIO. I bought a AutoAqua skimmer sensor but that needs to go onto a clear piece. Does anyone know of a sensor that will work?

It is more reliable to put the ato on a timer that runs for a set time (10 min??) A few times a day with a float. And never fill the ato container with more water than your system can handle without overflowing.
