O.K. guys, this is interesting. I have a fishy smell coming from my pool and I have a SWG (Eco Matic ESC 36). My chlorine level is <.4 and my salt level is at 5880 ppm. I was told I need to shock the pool. I have never heard of the SWG not working if the salt levels are too High or low. What should I do to best fit my needs?
