My salt level has been fine since early May after opening. I check chlorinator almost every day. 4 days ago reading was very low salt. I have put 40 lb of salt in 3 consecutive days still says very low salt. Tested water, chlorine level nearly zero as no chlorine has been made for 3-4 days. Water still looks good, not cloudy but I got desperate and dumped half gallon of bleach in pool to get some chlorine in it. Should I just wait and keep putting more salt in if salt reading continues to be low?
