To be sure I wasn't adding tainted water to my test I used a sample of boiled water from my tea kettle, and tap water which is provided by the city I live in and could be chemically treated for purity, and did a CYA test on both of those. Results were zero so I used each of these to do two dilution CYA tests. Pool temp is 61 degrees but both tests I ran I warmed the sample up before adding reagent to where it felt warm on my skin when drops were dripped onto wrist. How am I doing so far?
Next I filled the sample bottle with 7ml of pool water, and diluted it with each of those clean samples once, shook well, reduced the level to 7ml filled it with reagent up to 14ml mark and tested each sample. Both were over 100.
Emptied test bottle, refilled with pool water to 7ml, added each zero sample to 14ml, shook, reduced to 7ml, added both zero samples again, shook, and reduced to 7ml, and then added reagent. The results of both of those tests were 60.
Would I be wrong in my calculations if I said that my CYA level is 120? or is it 180 after 2 dilutions. <personal note, my math skills are 50 years old an weren't all that when I was in school >
You can laugh at me if you like, at least I can put a smile on someone's face today!!
