When I opened this year, my AquaChek test strips showed 760 ppm of salt (pool store showed 1000). I have since added 7 bags (20kg each). According to the pool calculator, 140kg should have raised the salt by 2157, so I am thinking I would be around 2900 (or 3150 if the pool store's reading was accurate). My strips are now reading just 2100 ppm.
Is it likely that my strips are inaccurate and I should trust the chemistry/math? Should I try a new package of them? I would like to have the K-1766 , but it is $49 + shipping in Canada (!?!) while only US$17, so I might try a new bottle of AquaChek strips first.
Side note- I don't understand why Taylor lets its exclusive Canadian distributor price gouge so blatantly...
