Ok, I just did a chlorine test again and got wildly different results from last night but they seem to be more in line with what I would expect though.

Free Chlorine was 22ppm
Combined Chlorine was Zero meaning it did not change to pink when I added the 5 drops of r-0013.

I can't explain the differences in the test results. I took the sample from the same place, in the same way. The only thing I can think is that the Chlorine was not dispersed well? But I don't see how that would be a problem, the pump is functioning fine and the return output is nice and strong.

But based on this latest test what should I do? Do I let the Chlorine fall now to maintenance levels? Or keep shock level?

Flummoxed.
