Yes, the FAS-DPD Chlorine Test. Which comes in all the Recommended Test Kits or you can get it by itself at the first link or Google for Taylor K-1515.
Testing result I do not understand....

The K-1515-A is just a DPD-FAS kit.
And in in response to your earlier posts, the new revisions of Pentair ICs cannot be recalibrated in the field. The older version could but Pentair found too many customers doing it incorrectly and screwing up their cells. Also, the Pentair ICs have an approximate temperature drift of +300ppm/5 deg F. So rain water is really good at chilling out the surface pool water and causing temperature related drift.

Thanks Jason. The only reason I haven't gotten a TF-1000 is because I have enough of all the other reagents for now having stocked up prior to becoming more active here and learning more. Might be a good consideration tho given all the testing going on to ensure sparkyitis ans expand my understanding of the chemistry.

Ah....very good to know! So one couls assume it would be better to wait a fay or so after significant rainfall and cooling to allow the sun to warm it back up and see.how the salt varies. That also explains why the other day it was 3050 and yesterday it was.3200 with no additonal added salt.

Yeah. Some SWG manufacturers add a temperature compensation factor to their output salt value, others, like Pentair, do not.
Don't waste too much time trying to over-analyze salt concentration. It's best to just stick to one test like the Taylor drops and determine an offset between that test and what the cell says. As long as the SWG is happy, it will produce all the chlorine it is supposed to. The cells chlorine output response is very weak with respect to salt concentration, ie, salt cells can operate with a very wide margin. If they were not so, it would not be economical to operate one.

Yep...That's my plan. I just wanted to verify salt cell was in range and not doing something wildly out of whack. The 1766 kit confirmed that so I doubt I have any need to do that test very often. And as you said, I have to keep the salt cell happy no matter what.
You seem like a bit of a gadget guy, so look up "Pentair IntelliWand". I don't think they're terribly useful, but you might like them

Now that's scary.... I just saw that in a long ago thread I was reading and went and looked it up.... And then you post this. Are you looking over my shoulder? Lol..
Was also reading today about IntellipH and IntelliChem.

The IntelliPH is on my equipment plan for next season.
IMO, I think the IntelliChem is a huge waste of time and energy. ORP measurements are just not strongly correlated enough to FC to make them a useful proxy (too many confounding variables) and, while stable and reliable, pH probes are just another expense. I much prefer the simplicity of duty cycle based dosing methods. Much easier to debug.
My $0.02 for what it's worth.

Yes. I'm not planning on IntelliChem. Seems like much more sustainable and reliable results from IntellipH from what I've been reading.
In the description of the K1515a it says either 0.2 or 0.5 ppm Chlorine.
Since I don't have it yet, how would you know which one applies...0.2 or 0.5?

Water sample size. If you use a 10mL water sample, the titrant gives a 0.5ppm/drop accuracy. If you use a 25mL sample, then the accuracy is 0.2ppm/drop.
Typically when you SLAM, you need to do A LOT of testing so using the 10mL sample size helps conserve titrant.
IMO, you should stock up on the titrant. I get 2oz bottles on Amazon from Amato Chemicals for ~ $8 bottle.

Thanks. Was looking around at the prices and amazon has the best price from anywhere else I've seen.
Didn't I read in one of your threads that you were going to buy the tf-100 or the Taylor k-2006 kit? Both of them have the fas/dpd test you are asking about. Whoops missed the 2nd page. You can also get a16 oz bottle of the 0871 directly from Taylor or Amazon for less. You can count on it being the freshest from Taylor though.
Taylor is definitely the slowest and most expensive route.
Amazon has several vendors for the chemicals (Amato, Marks Pool Store, etc)
I don't think freshness is a big concern. As long as its in a Taylor bottle, it should be marked with a Lot ID and traceable that way with one phone call to Taylor's help line. If the reagent is old, then Taylor can tell you that.

Thanks. I'm sure I will get the 100 at some point in time when all of the current stuff I have starts to run low/out.
Problem is, you won't know the lot# until you get it. That's too late! I got mine from Taylor in just a few days, while it took more than a week to get my k-2006 thru Amazon. If it were the r-0013, I wouldn't worry about freshness either, but the 0871 is more sensitive. Bob, if have all the components except for the fas/dpd (which I believe your getting anyhow), then there's no real reason to get the tf-100. Just by refill bottles when needed. Then don't wait till you only have one test left.
Thanks all. I've got a Taylor 2005 and the 1766 for salt and I will get the 1515a. I think that will get me all the tests that are important?
