I put a few bags in our pool mid - season last year and did not tell the wife I had done it. The very first time she went in she commented on how nice the water felt.

This summer we topped up the salt to 2800 ppm and put in the SWG system.

The only negative we've seen so far is that water that gets on top of the *&^%%$$ solar cover and evaporates, leaves a bit of white powered. A few minutes of hosing or a rainfall clears it.

Even at the levels this year that are much higher than we had last year, I still prefer it to straight fresh water.
