My Pool Service (recently srarted) has a SGS Instruments SLDT Salinity/Conductivity/TDS meter that is NSF international certified and by which he swears by for accuracy. I have tried all manner of tests for salt and finally stayed with the strip test which I have been using for over two years. The salt test with the Pool Service meter and my salt test with the salt strip are consistently 1000ppm apart (eg meter 4750 - strip 3750). My SWG owners manual calls for maintaining my salt level @ 4000ppm. I can live with a reasonable difference between the two tests but fear that a 1000ppm may be to much of a difference. I would appreciate any comments / recommendations.
Also ... can a higher than normal salt lever cause calcium deposits?
Thanks.
