How often are you'll adding salt?

[pooldv]

None. With no rain or splash out the salt will stay there forever.

So again, in a perfect pool world how much salt should I be going through with no rain dilution?

None.

With no rain, no splash out and no water loss of any kind, you salt would only increase since most municipal water supplies have a salinity of about 50-200ppm.

This is exactly my case - I get 10" of rain per year and 90" of evaporation. I have low splashout and I don't backwash. My salinity creeps up annually and I have never added any salt in 4 years.

56 inches per year here. 600 sq ft pool. Lots of overflow.

This is exactly what I was thinking. I don't know how you could have no excess water unless you live where evaporation exceeds rainfall consistently week to week. If there's no overflow line fitted on the pool, then I would think about filling the pool up a bit high, and then doing the bucket test. I'm wondering if there's a leak around the level you like to keep the pool at.

And yes, 2" per week evaporation is possible, just not very common. You would need wind across the pool, low humidity, warm water and/or water features.

But yeh, if it never overflows, there's no splashout, and the pool doesn't leak, you would never need to add salt.

The range of salt additions for different pools arises from the many factors talked about in this thread, such as minor or medium leaks, rainfall leading to water flowing out through an installed overflow line, water pumped out to drop the level or to backwash, or high use of the pool causing more splashout.

On Sunday last, we lost at least a pound from the water-gun battle of the century!!

Great, thanks for everyone's feedback.
