Replying to my thread...I still don't have the salt system running correctly. I did have the water tested at the pool store. It was 3900...too high. I drained about 14" and added fresh. We have also gotten about 2" of rain. The stick test still says 3650. The system isn't reading correct. It says 2000. The cell look new. The board seems to be operating correct. I will try draining and adding again to see if I can get it to drop at least to about 3200. Is anyone familiar with the Saniclear 40 system. It is difficult to find information about it.
