The best way to maintain a Crystal Pure Pool Salt System (20,000 gallons) is to regularly check and adjust the salt level, clean the filter, run the pump and filter system for 8-10 hours per day, and test the water weekly.

You should add salt to your pool every 2-3 weeks to keep the salt levels in balance.

If you notice that the pool water has become cloudy or the chlorine levels are low, it may be time to have your pool serviced by a qualified technician.

You should use a high-quality food grade salt such as Solar Salt, Diamond Crystal Salt, or Morton's Pool Salt.

You should aim for a salinity level between 3,000 and 4,000 ppm. To achieve this, you should add roughly 2.5 pounds of salt per 100 gallons of pool water.
