Pool store PH results today was 6.9, my result was ~7.6 with home test kit. Reagent is less than a month old.
Pool store says salt is 3200, same as last test 3 weeks ago before several inches of rain and no added salt. I do not have a home salt test.
My FAS/DPD was 4.5, pool store says 4.3.
The confusion is that it seems their chlorine test is matching mine, PH test is drastically different and salt is obviously wrong unless the copious rain was salty.
Is this the point where I completely distrust their results and go with mine, or go with their computer test?
