We have a mineral springs system which has worked great for 2 1/2 yrs. This year, it started working and then we may have put too much salt in it. It is now showing a salt reading of 1600 when two pool stores have said it has a salt level of 4000. I have called Goldline and got two different opinions. One said that we should drain the pool 12" and refill with city water and the other said our cell is bad!! It is under partial warranty and will cost between $350-400. Does anyone have any suggestions? What should we clean the cell with? Thanks for your ideas before I purchase a replacement!
