I Want To Be A B/b/b Convert!!!

A few notes about the Aquachem test kit.
First it uses OTO to test for chlorine. OTO is not a reliable indicator of FC. It is really only a test for TC. You need a DPD (turns pink) or an FAS-DPD
(Titration test and very accurate, even at high chlorine levels and can detect as low as .2 ppm CC)

Second, there seems to be some issues with the CH test in this kit. It does not produce reliable results under certain conditions. Check out this thread for more details.

Hope this helps.

Went back and read the thread you posted. That's the kit I have and the exact results I've gotten!!! Worked fine the first time and now the first solution does not even change the water sample to violet. I'll have to try the 8-10 drops and see what happens. There is a "disclaimer" of sorts on the instruction sheet. Across the top of the instructions for pH, Alk and CH tests it says "Do not perform following tests if total available chlorine exceeds 3.0 ppm." So, I'm guessing that this test kit is crap when attempting to clean your water and balance it at the same time???

I may be wrong, but I 'm wondering if perhaps the chlorine readings are off. Having a CC of 3 is pretty high especially since in her earlier post it was .6. I would recheck those numbers.
