How long it lasts
Replace it when the cell plates are worn or calcified and the unit no longer produces enough, Zodiac says; clean the electrode first if you see scale.
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.
