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!?!?!?
