Ok so I have an AutoPilot RC 35/22 and I started getting a Check/Clean Cell message. So I bought the Muriatic acid and did the 80% water 20% acid thing for 20 minutes which did clean off the small amount of build up I noticed. So now it seems to rotate between the Check Clean Cell and Low Amps/Cell? message randomly. It is an 19000 gallon in ground. Attaching a pic of the info needed I think. I'm not sure what the amps and volts should be to begin with. I apparently need to add 31 lbs of salt according to the test menu. So will just adding salt fix the issue? I have been reading the salt levels can change the voltage levels etc. Any direction here on trouble shooting would be helpful and appreciated. I don't want to just throw $250 at a new cell and hope that fixes the problem if it could be something else.
