Well now I am perplexed. The k-2006 cya test is showing worse than before I drained and refilled I took it this AM and again tonight. I can't see the black dot after about 10 dropsof the 7ml of pool water the filling with R -013 to the 14 line and shaking it up, now I am out of that reagent . However the test strip and leslies both have me at under fifty. Leslies gave me a 30ppm for CYA. What the heck am I doing wrong? The pool is clearing out now but this cya is driving me nuts.
