I am curious about this also. Just starting my AGP now and its my first time starting a winterized pool. I am assuming the sensor on the chlorine generator that is less than a year old is still going to be pretty accurate and can be trusted more so that the pool store salt strips?
UPDATE: My SWG is reading 2600ppm and the test strips I recieved with the SWG last year say its only 760ppm. I am having a hard time believing the salt level is that low when I only took 4 or 5 inches of water out of the pool when I closed it last year. I am going to buy new strips from the pool store today to see what those say.
