How long it lasts
Replace it when the controller shows Check Cell and cleaning the electrode in mild acid does not clear it, Zodiac says; fit the electrode made for your model.
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.
