Because you have to test for a much higher level of chlorine, you may want to invest in a FAS-DPD test that can go much higher reliably. I think it will measure up to 50 - not that you'd be going quite that high... While the dilution/shot glass method will work, I never felt all that convinced that my results were correct, so I was quite glad when I received my kit that included the FAS-DPD for chlorine.

It's possible to buy just the FAS-DPD test for chlorine without buying an entire kit. Look for CarlD's reply #6 in this thread:
