free chlorine testing question

[chem geek]

The phone rep is wrong and is probably confusing the K-2005 which has a DPD chlorine test where you compare intensity of pink with the K-2006 which has a FAS-DPD chlorine test where you count the drops until the pink turns clear (i.e. uses titrants). As Watermom noted, the only difference between the K-2006 (A) vs. the K-2006C is in the quantity of reagent bottles where the former uses 0.75 ounces and the latter uses 2 ounces. So the "C" costs more but is more economical per test. You can get the K-2006 at a good online price here and can get the K-2006C here.

Thanks for the reponses

Are these test kits easier to obtain f/c readings than how im currently doing it.
Seems like the most recommended kit is the k2006

It's much easier to test FC with these kits, and WAY more accurate, since you're not comparing shades of yellow. Rather, you're watching for a complete change from pink to clear. Besides, it will allow you to test for CC, which is a major factor when clearing up a green pool.

The K2006 is the most recommended kit around here. I know it's pricey compared to the OTO, but it will eliminate the need for pool store testing, which usually isn't as accurate anyway. It will save you its price tenfold in time, chemicals, and aggravation, because you'll catch a potential problem before it gets to be major and can get it fixed.

The K-2006 is the most recommended over the K-2006C because of the price difference. Most people are already somewhat hesitant to spend that kind of money on a good test kit even though it will save them lots more than that in the long run. However, the K-2006C has greater quantities of the reagents, so you won't need refills as soon if you don't mind paying an extra $40. (it does have more than twice as much of the reagents: 2 oz. vs. 0.75 oz. for most things.)

If you want to get something with more quantities for the FC tests you do most frequently, then you can either mix and match by buying the Taylor K-2006 and supplementing with extra DPD powder (R-0870) and FAS-DPD titrating drops (R-0871) or you can get something like the TF-100 here that has more of the reagents you use the most often (it's sort of like Ben's test kit he used to sell) including the CYA test reagent. A comparison of these test kits is in this post.

Just orderded the TF-100xl.Was a good alternative to the other rec kits and the price was better. Hope i made a wise choice, but seemed like that was also a recommended kit.
Looking foward to accuratly test my water.

The TF-100XL (which uses Taylor reagents) is useful if you are going to be shocking your pool and doing a lot of high FC measurements using the FAD-DPD chlorine test. Just keep in mind that some of the reagents don't last forever, but if you store them in a cool dark place then all should be good for at least 2 years (Taylor recommends changing them every year, but that's being conservative). The indicator dyes, such as used for the pH, TA and CH tests, and the FAS-DPD titrating reagent are the most sensitive; everything else will last for many years.

Taylor has a nice article on Recognizing a Compromised Reagent.
