I have a couple of questions concerning my SWG pool. I have a Pentair IC-20 Saltwater generator giving me an indication that the salt level is low ( with this indication the generator is NOT making chlorine ). When I test my salt level it is reading approx 3000 ppm. When I call my pool rep, he tells me the level needs to be at least 3400 preferably 3700ppm in order for my generator to work. My CYA level is fine, but he also teels me this has to be at least a certain level, is this true? Having said all this and having previous problems with my SWG my rep is telling me in October there is a new SWG coming out that he is going to replace. Worst case scenario with my SWG inop until October, will I be able to supplement with large chlorine tabs in my skimmer and maybe shock once a week? What would be best with my worst case scenario? By the way I have a 19,000 gallon vinyl inground with a Pentair sand filter, 1HP pump. Thanks.
