I changed my cell last week. My drop test showed 2800 and the swg showed 3200. The other day I added some water to the pool and then we had a significant rainfall. I retested today and now I have 2600 vs 3300. The new cell was left by a previous owner (in sealed box when I moved in) so it is at least 9 years old. I went from a T-15 which I was pretty accurate before it started failing at the end of last season to this T-9. I did the off/auto calibration and it does not drop below 3300. The only other change this year was adjusting my pump schedule so it runs higher overnight and lower during the day. Also when I opened the pool this year I did not have to add any salt which surprised me. I normally I add 1-2 bags. I figure I must have added too much salt last year due to faulty cell readings.
I have replaced the swg limiter 3 times and was told that high salt can cause this to blow so I am trying to keep it at the lower end. Ideally I would like to avoid buying a new cell since I have this brand new one. If I do, I am concerned that it will end up being an issue with the control panel. Advice??
