Just to be sure I'm reading this correct.
I mixed 1ml chlorine in 100ml distilled h2o then mixed 1ml of that in another 100ml distilled h2o.
I took 10 ml of the final solution (10,000:1) and tested it using the FAS-DPD method.
It took 11 drops make it clear.
So, does that mean the chlorine % is 5.5?
