Yesterday I posted a question on the accuracy of Aquachek pool strips, versus pool unit and the Taylor salt kit.
Thinking about this overnight I came to realize there might be a way of confirming the accuracy of the strips and Taylor salt kit but I do not know how to this. However I think I understand the principal but not what quantities are involved and this is where I need help.
For a given amount of water and a given amount of salt mixed together it should be possible to create a test solution that gives say 3500 ppm of salt, against this base liquid I could then use my test strips and Taylor kit to see if they are functioning correctly.
By my calculation 2.22 gallons of water which has a starting pH of 7.8 and an alkalinity of 80 (with no calcium, CyA or borax), added to 1 oz of salt should register 3500 ppm, but I am not sure if this is correct.
Or perhaps better still is there a test solution one could purchase?
Help would be appreciated.
