Testing pH, AL, CH with high CL

[fcfrey]

Catnip --- Your original question concerned the accuracy of the pH test when the Cl is above 3.0 ppm.
My answer is based on my experience. Yes it does bleach out using phenol red pH test.
I'm not sure what pH method is in Ben's kit, as I said I have a menagerie of Taylor kits (that's what happens if you don't get educated here first).
I have had electronic testers and sent them all back, because I didn't see a significant difference when adding a drop or two of thiosulphate and didn't want to spend te extra money.
Ben's kit does include the FAS-DPD method for Chlorine which is a much better test than the standard DPD method (using colorimetric comparison). The FAS-DPD test has a definite end point and is capable of testing high levels of Cl.

Hope that clears up my original answer.

Again Ben's kit is a great value for the complete package. Like I said before my Taylor menagerie cost me well over $300.00 combined (too soon old --- too late Smart)
