I bought the test kit last a year and half ago. Historically, my results and Leslie's have matched or been very close. Now they are significantly different which has me wondering who is accurate as I am using a good bit of acid for my 10,700 gallon salt play pool.
TA me= 45. Leslie's = 90
CH me = 675. Leslie's = 320
Cya me = 60. Leslie's = 30
I am most worried about the calcium hardness and total alkalinity.
Any suggestions? Is my regent perhaps bad?
