Read this on the Extended Test Kit Directions re: CYA testing:
•If you are using the large view tube and know that your CYA level is at least 50, you can use half as much pool water and half as much R-0013 to save on reagent.
I have the lg tube from the TF100 and tried to implement this, but I don't think it worked right. I assumed to "use half as much pool water" that I would estimate this by filling with water halway between the lower mark and the bottom of the bottle, and "half as much R-0013" that I would then fill up to the lower mark. I can't recall what the results were, but I remember it did not mesh up with what it had been the day before. Therefore, can anyone, or you Jason, explain what was meant by the above bullet?
Tx.
