Hi, My name is Tyrone. First I want to thank all of you for the wonderful work you'll are during. My concern is with testing with the ' CHLORINE DIOXIDE'' test strips. You sent me some instructions on how to mix the CDS 3000ppm. The test strips that you have is the same ones I have ( INSTA-TEST ANALYTIC 0 - 10 - 25 - 50 - 100 - 250 - AND 500 ). There is no 300 color testing chart for me to match to, to determine a 3000ppm strength of my final CDS SOLUTION. I have searched the web,, called numerous water purification companies, but with no success finding test strips that have a 300 color test square included in the scale.Tell me, what do you suggest. Thanking you in advance for your help.
Tyrone.
