Thanks for your help everyone. Quick and/or dumb question for you. It looks like the Taylor K-2006 only tests chlorine up to 5.0 ppm. How do I know if I've got the level up to the recommended 20 ppm?

I think you are confusing the K-2006 with the K-2005 since the K-2006 does not use a comaparator but is a drop counting test.
The k-2005 is the testkit that is usually carried in stores since it is a bit less expensive (the kits are identical except for the chlorine tests.
The chlorine test in the K-2006 is far superior and easier to use so this is the kit you want. In most areas of the country it is not stocked so you will most likely have to order it online.
