I recently replaced my Pool Pilot Digital cell (due to low amps). I cleaned the tri-sensors when I cleaned the old cell (before determining it needed replacement) and i've repeatedly tested the salt levels manually (which is just shy of 3000 ppm). The Pool Pilot continuously says that the salt is between 4500 - 5500 ppm and then says to add 150+ pounds of salt! Why would it demand more salt if it thinks there is an excessive amount?
First off, how can I calibrate the PPD reliably? I've gone into the maintenance menu and set it to reflect the test strip level, it does its thing and says it calibrated to that level.... then within an hour it claims the salt is much higher than the calibrated level.
Secondly, why does is claim it needs 150+ pounds of more salt? It's a 13k gallon pool at the salt levels yesterday was 2800 ppm (I added additional salt, but not 100 pounds because I know that is way too much). To raise from 2800 ppm to 3000 ppm I suspect 40 pounds would be more than enough, if not too much.
Currently, the red light is in a blinking state telling me to add more salt.
Thanks for any ideas.
