Starting 12th season with same T-15 cell

[wpturner05]

Good morning,

I am beginning my 12th season on the same/initial cell that I installed upon switching to salt water in 2014. I don't mean to look a gift horse in the mouth, but this seems long. Last night I tested to be sure it was still working by putting it at 100% for 12 hours overnight and my FC jumped from 5 to 9.5.

I purchased a new T-15 cell in the summer of 2023 feeling certain that the cell would eventually stop working. Here I am. It is still working.

Do I just leave the same cell in place until it no longer produces chlorine?? How do I know when to replace the cell?

With an Aquarite system monitor Ave Salinity reported by the system diagnostics versus actual pool water salinity tested with a K1766 kit. When you get to 75% (ave salinity over actual salinity), it is time to replace the cell.

Marty - I apologize. I do not understand your response. What does that mean?
