Does evaporation/auto fill lower salt levels?

I have them same issue with salt dropping. I have a 17k gal pebble tech bottom pool in southern California. I do have an auto filler and it trickles most of the day. However, our pool also has an attached jacuzzi which we use quite a bit. So with kids jumping in and out and steam from the jacuzzi the auto fill dribbles throughout the day.

Does evaporation/auto fill lower salt levels?

Thank you in advance,

Steve

Evaporation and refilling does not lower salt levels. Both splash out and leaks followed by refilling does lower the salt level.

If you salt level is going down noticeably, you either have an huge amount of splash out, or you have a leak.

Is there an average of how often/how much salt is typically used in a 17k pool? I do not have huge splash out.

Thanks in advance.

I only add salt once a year when I replace some of the water. If you don't have splash out, then the only other cause would be either a leak or the salt cell could be failing if you use that as a salt measurement.

At least this spring/summer in Houston, rain is my biggest reason for loss of salt. Rain is filling the pool and water is flowing out the overflow.

The fact that your auto water leveler is running constantly means you're losing water somewhere. If you turn OFF your automatic water leveler, a dropage of your water line will indicate how much water you're losing.
If you have a chance to do this with no one using the pool or spa, would confirm a leak.
