Just so you know: there is just one "decent test kit" that's widely available locally: the HTH 6-way kit, made by Taylor and sold by some Walmarts. It is fully compatible with the K-2006, and since the chlorine test is OTO, it continues to work when chlorine levels are above 5 ppm.

The Taylor K2005 is sometimes available locally, and is a good kit for everything EXCEPT testing chlorine. But, since it uses the DPD color match test, a zero chlorine reading can mean you have NO chlorine **OR** it can mean you have more than 10 ppm of chlorine. So, until you get a HTH 6-way OR a K-2006 DPD-FAS kit OR a K-2006 PLUS the Taylor 1515 DPD-FAS single function test . . . you do not have a good kit.

There are a very few other kits that have the DPD-FAS test, but they are not widely available.
