Taylor drop based reagents are all I use. The Taylor website lists all of their colorimetric and titration based tests. The K-2006 is your basic residential pool test kit that contains all the tests you need to perform on a regular basis. All reagent bottles are 0.75oz size which can be a bit on the small side if you need to do a lot of chlorine testing. The K-2006C is their "commercial" kit which is exactly the same as the K-2006 but with bigger 2oz bottles of the reagents.

Since you'll likely be doing a baqua-goop conversion, it would be my opinion that you should go for the larger kit (K-2006C) or get the smaller kit and couple of extra 2oz bottles of the chlorine titrating reagent.

I've always ordered via Amazon with the supplier being Amato Industries (based in Washington, DC). Always had great service from them. I see PF has its own Amazon shop so you can use that and support PF by purchasing through that. Either way, very few local pool stores carry Taylor chemicals or their full kits.
