I have a chlor-ease swg. what can I use to clean the cell. I am having problems with no chlorine in the pool. I have shocked and it was good for about 3 days then back to 0. I need some help trying anything and everything before sending it back for then to evaluate the swg to see if it is a manufacture defect, they say it will take 3 weeks to do this. Thank You for any help you guys can give me. Latest readings salt at 3700 TH 0, TC 1, FC 1, Ph 7.6, TA 80, CYA 50. Thanks again.
