Testing chlorine with Taylor K-2006 kit?

Al is right. The 25 cc measurement produces a more precise measurement....but probably is not necessary for normal tesing....It's a swimming pool, not rocket science! Your difference is 2 ppm and that is not going to make a lot of difference in your pool at chlorine levels that high. It's still a lot more precise than you would get with a DPD or OTO test, both of which would need dilution to get readings that high with available test kits!

Thanks Al and waterbear. I am still in the conversion process so I was trying to keep the chlorine at shock level, which with 0 CYA is 10ppm. And these were first thing this morning readings so it seems my chlorine held pretty well overnight.

I did measure with a syringe and both 10 and 25 were slightly above the mark on the tester.
