Mixing station siphon stop?

[aaron186]

I just built my mixing station. When I pump water from the RO into the salt bin, the pump auto shuts off when dry. It was a leftover pump and I don’t want to replace it. That means if I don’t watch it closely, it creates a siphon of salt water into my RO bin when the pump stops. What’s the best way to ensure no salt water gets siphoned into my RO bin? I could cut the pipe above the water but I like using the pump to stir the salt.
