CH test reads 0?

[waterbear]

I have the same Walmart test kit (among others) and had the same problem with that test. (My indicator was NOT leaking) I found out by experimentation that the test works properly if you put about 8-10 drops of the indicator in the water instead of just 2 and have verified the results by checking it against my Tayor test kit and it was pretty close. (the Walmart kit has an accuracy of 50 ppm while the Talyor kit has an accuracy of 10 ppm)

Hope this helps.

Waterbear, that definitely helps. I'll give it a shot tomorrow with 8 drops and see what it reads. I just hope I didn't make the water too hard by believing the walmart kit.

Can y'all photograph that kit, and post the photograph?

In some parts of the country, the kit Walmart sells *is* a relabeled Taylor, often under the HTH brand. I'm not sure what you've got there, but it's not Taylor. With two kits from different areas, odds are that the kit is 'defective from the factory'.

People need to be warned against it, if this is more than just a coincidence affecting two kits.

PS: It would be great if we could ID it, get everyone to test their test, and then get everyone with a bad one to take it back. Walmart's inventory control system would almost instantly flag it as a quality control problem, to be 'discussed' with the manufacturer. And trust me, you do NOT want to be having that conversation with Walmart, if you are a manufacturer.

Here are the pics of my kit. Intersting to note that I am in St. Augustine, Fl and cygnusecks is about 2 hours away in Orlando, Fl! Might be a regionally distributed kit. I think the quality control might not be very good. The first one I got had a defective Cl/pH comparator...the color bars had come unattached on the Cl side and had moved out of position and the tube was cracked so I returned it for the one I have now. Also, the Ch test is different than Taylor's. There are only 2 reagents...indicator and titrant, no calcium buffer (reagent #1 in Taylor kit)
