In my case, I keep the water temperature at 33 degrees in winter.Hayward SWG cells do not have a conductivity sensor. They use volts and amps to calculate a salinity. The calculations can be thrown off by water temperature as higher water temperature draws more amps and it reads higher salt.
Use a salt drop test to determine your actual salt level.
In the SWG cell, it comes out as 3000, but can it actually be lower?
