Which test kit?

[AE340B]

I ordered Ben's kit last year. Eventually I got a refund as it never arrived. What make and model complete test kit do you folks recommend, and where is the best place to get it? Thanks!

The Taylor K-2006 has the same functionality as Ben's kit. Most of the tests are identical (except for the pH, which is just as good and the acid and base demands that Ben's kit doesn't have. IMHO, for good reason!) If you want to add the OTO total chlorine test and the same pH test as Ben's kit than you also need a Taylor K-1000. The OTO test is good for quick daily checks on your clorine level. If you need the salt option then Taylor has 2 kits that will fit the bill K-1766 and K-1771. Either one is funtionally equivalent to Ben's. As an alternative you could use the AquaChek White salt test strips. This is one of the test strips that actually works. It uses the same chemistry as the Taylor kit and I have found it to be reliable. I have checked it against the Taylor kit and against both a Goldline and a LaMotte salt meter many times and the strips were always right on the money.

Check this thread located just a little before this one.

SPS seems to be among the best for prices and delivery. I made some comments about ordering extra reagents in that thread. Here's the link to SPS.

I took a quick look on Taylor's website and didn't see what the real difference is between the K-2006 and K-2005 test kits except that the K-2006 kit is more expensive. What did I miss?

K-2005 is a DPD test kit. K-2006 is a FAS-DPD test kit.
BIGGGG difference!
DPD you can only test to 15ppm on your chlorine.
FAS-DPD you can test to 50ppm or even 100ppm.

We recommend the K-2006 or K-2006C (more reagents).

However, the Leslie's FAS-DPD Service Test Kit is similar and you can get it instead. It's simply Taylor re-agents in a Leslie's box.

How often would I see CL, CC or FC, above 15 ppm? I guess if you get a big problem CC could go high, but FC? By the way, what is FAS-DPD; is it an acronym or ?

If CC is over 15ppm you have a problem. But FC as high as 25? Sure.

If your stabilizer level (CYA) is over 100, you have to shock by getting FC up to 25ppm. You maintain your pool at something like 12-15ppm (I've forgotten exactly).

Unless you have very low CYA (20 or less) you normally will shock to 15ppm of FC--that's now at the limit of standard DPD kits. Past 15ppm ordinary DPD can bleach out and look like 0 ppm! Use FAS-DPD and you have lots of headroom.

DPD and FAS-DPD are the reagents used.
DPD is N,N-diethyl-paraphenylenediamine. It is the indicator used to test for clorine (and other halogens) using a color comparator. Most men have difficulties with this test because they cannot differentiate between the shades of red the test produces. The test can bleach out at chlorine levels above 10 ppm (which is not even shock level in most pools!). It is accurate to 1 ppm (IF you can differentiate the different shades of red produced.) It can test both free and total chlorine so combined chlorine can be found by the formula TC-FC=CC

FAS-DPD stands for Ferric Ammonium Sulfate -- N,N-diethyl-paraphenylenediamine
This test does not use a color comparator but is a titration test (like the tests for Total Alkallinity and Calcium Hardness) with a distinct endpoint color change from bright pink to colorless. Even people who are colorblind find this test easy to do. This test will not bleach out at chlorine levels as high as 50 ppm with an precision of as much as .2 ppm. (Comes in handy when you want to try and kill algae and it requires you to keep your FC levels at 15 or 20 ppm!) It test for free chlorine and combined chlorine directly. If you want to know your total chlorine it would be FC+CC=TC.

All things considered the FAS-DPD test is much easier to do and produces much more accurate results and is worth every penny extra it costs!
