I have an AutoPilot Salt Chlorine Generator and am confused about the salt levels its reporting versus what testing at the pool store says.
Yesterday morning I got the water tested at a local pool store and they said it was 2500ppm and recommended one bag (40lbs) of salt. Before adding, the autopilot was reading at 3500ppm, so a 1000ppm difference from the test.
This morning the autopilot said 3400ppm and when I brought water to store again they said it was at 2700ppm and said to use another bag of salt to get into the 2800-3200 range.
So I am pretty confused on what the difference is between what the AutoPilot LED is telling me and what the water is registering.
