Proper testing explanations and pics from Taylor Technologie

[Buggsw]

I've noticed many people having trouble determining whether they are evaluating tests for CYA correctly among other tests.

The Taylor Technologies website has a lot of information on proper techniques and a few demonstrations or pictures.

Here is a link to what you should see when you test for CYA. (Scroll down for pictures)

Here is a link to seeing colors, such as when you test for TA.

Here is a link which you will find another link "view demo" which will show you the FAS/DPD test method.

There is a plethora of great information at their site. Hope you enjoy it and find it useful.

Thanks Buggs, that is very informative.

Exactly what I needed, as I have this issue;

5. I got a purple endpoint instead of a blue endpoint when I did a hardness test. What happened? There are metals interfering with the test, most likely ions from algaecides, pipes, or even the source water itself. To avoid this problem, add five or six drops of titrant to the sample before adding the buffer and indicator, then proceed normally with the test. Always include the number of drops of titrant added at the beginning of the test­­ when counting the total number of drops required to reach the endpoint.



So what is titrant that I should add before the buffer and indicator?

I'm using the TFP testkit, does it include titrant?

thanks,

In the CH test, the titrant would be R-0012. I'm not sure if Dave has renamed the regents in his kit but it should be the last reagent you add then count to determine the ppm.
