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

[waterbear]

KurtV - It's an AquaChem test kit......I know....not the best but all that K-Mart had. I just retested the cl and hardness. The Cl appears to be a bit above 3 but not to 5 and after waiting a few minutes for the sample to develop it really doesn't change. So I guess, in all actuality, the CC is the same as FC??? Is that right?

Now the hardness testinstructions say to "add 2 drops of solution A....sample with turn violet if hardness is present." My sample does not turn violet. However, it did this morning. Then I'm supposed to ad solution B in drops until the sample color changes to blue. This morning it took 3 drop to change to blue which made the hardness 150ppm (multiply # of drops by 50). This afternoon I had to add 36 drops to get the sample to turn a very pale blue. So that would make my water hardness 1800ppm???? This can't be right!?!?!?

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.
