Unless you've added salt quite recently and it hasn't fully dissolved yet, it's pretty unlikely that you have salt settled at the bottom of your pool. Saltwater pools are salinated to 3-4,000 ppm and the "saturation point" for salt - the level at which salt can no longer dissolve - is around 260,000 ppm and the ocean commonly measures in the 30,000 ppm range.
The most likely situation is that you have Calcium Carbonate flakes forming and settling to the bottom. Test your water in order to <a href="https://www.orendatech.com/pool-dosing-calculators">calculate the Langolier Saturation Index</a>. Also referred to as LSI or, simply, the Saturation Index, LSI is a measure of water balance with at one end of the scale, the water is very caustic and can etch pool and pool equipment surfaces. At the other end of the scale, your water will be prone to rapid and excessive scaling with calcium carbonate which can also manifest as white flakes in the water.
The calculator will allow you to determine the effect on LSI of adjustments to different components of the LSI. Commonly, a reduction in pH and/or lowering the Calcium Hardness will do take care of the situation.
