I have a salt water system. My hand held salt dip tester reads about 3200ppm on a 15x24x54. The swg is reading around 3200 when it first kicks on the shoots up around 4400ppm and flashes high salt. The store employee said to go by what the generator reads as it cycles the whole pool and not just the cup of water from the salt dip tool. What are your thought on this? My first swg was 3 months old and started flashing high salt. It did t have the lcd for ppm readout. They replaced it with this new one.
