I'm trying to get an accurate reading on my CYA level, and want to do the test the same way with the same lighting source and the same amount of pool water & R-0013 for the sake of consistency. Evidently I stink at consistency and reading tests because I get wild swings in readings. Doing a quick search I found Jason's prescribed CYA test: extended-test-kit-directions-t25081.html
In it he describes a 15 ml pool water and 15 ml R-0013 ratio. Cool. So I go to measure my CYA test bottle and the instructions say fill to the bottom label with pool water and to the top of the label with R-0013. So now I measure those amounts and the ratio comes up to be 15 ml pool water and 18 ml R-0013. My ratio is and has been off. What's my CYA level? I don't know!
Could someone please clarify for me what level of water sample and reagent is accurate? I'm not doubting Jason, but from 2 sources of TFP I'm getting a confliction. For some reason I had written on my CYA test instructions, 14.6 ml pool water and 14.6 ml R-0013. I haven't a clue where that came from.
