4 year salt cell keeping 12,500 a pool Cl at 4.0. During my 90 day check on the cell I found a black rod on the bottom of the cell. Looks like the plastic retainer that was holding it in place broke off. Is the rod some time of anode?(see attached) All current and voltage reading on panel are in the normal range. I assume it time to replace the cell? Any idea why it broke off? I assume normal wear and tear?
Thanks for your input.
