Back in January the salt level reported by the SWG did not agree with pool store readings but the water temp was very cold so did not worry about it based on what I had read on this site. Now the water temp is up around 69-70 and I have a 1000 PPM difference between the SWG readout and pool store test results. Test today was 2700 PPM from the pool store and 3700-3800 reported by AquaPure. Had the same results two weeks ago at a different store.
What could cause this and how to correct? Pool was just installed in December.
