Great forum. It's so nice to get help from someone other than the local shop monopoly.
Anyway, overnight my reading went from 3000ppm and generating to 200 ppm and check cell light.
Could this still be the thermistor issue? I know others had said that lack of a power light was generally a symptom of this. My lights are all on as would be expected in a low salt reading situation.
Does this sound like the cell itself went bad?
I have the Compupool TCell 15 and an Aqua Rite control Board.
Thanks very much.
