How long it lasts
Replace it when the low-salt light stays on even though the salt level is right and the cell is clean, Zodiac says; fit the cell made for your model, or the chlorinator will not work properly.
After replacing: No reset needed. Once water flows through the new cell the controller reads it again; set the output again if you changed it while the cell was out.
