The label on my mixer bottle also allows for more reagent then pool water which has also been giving me a reading of 50ppm of CYA...

Could someone clarify the correct mix so I can be sure of my reading...

p.s. I purchased a p234 from ben this summer and with it, and the arsonal of information from this site, I have converted 5 friends to BBB and have become a "pool guru" to my friends.... Thanks to Ben and the rest of the forum members for a "Fantastic" site.
I don't believe an excess of the reagent is going to cause off results since the precipitaton is going to be in the reaction with the CYA in the water and once it has all reacted then an excess of reagent should not cause any problems. I could be wrong on this but I don't think so. The correct mix is equal parts of each.
