    CYA question

    So I have a 28K pool and every year I add 1/3 new water to my pool to get my CYA down to 30. This year they checked it and said its zero. I asked how that's possible and they said it dissipates over time. Is that true?

    Question on adding salt.

    Is the only benefit of adding salt to a pool without a SWG to make the water softer? Other question do you have to use a different test kit if salt is present in the pool? How much do you add in a pool 25k without a SWG? Thanks
