 Just not set right for the water. They're not dialed right in. So they burn a lot of salt. So they're putting all these chlorides down the drain and different things. And those things do leach to our rivers and streams, different things. So with my system, I have just dialed right in. So, I mean, the salt use, it all depends on family size water use. But on average, my customers use maybe 10 bags of salt a year. So very, very efficient. Yeah, not a lot. No, no.
