Low water shutoff recommendations please

[Swalker]

I’m looking for a simple float/sensor installed in my pond that will shut off my pump should something go wrong.
I have an external pump.

Thank you

Check out the various online pond stores like Webb’s, underwater warehouse, pond guy. There are tons of float switches out there.
